#Comets
1 messages ยท Page 8 of 1
How come there is no tail visible in this view, I thought it's very bright
the weather finally seems extremely favorable today ๐ ๐
ok so either my plan didnt work and is showing artefacts or it does work and the comet is spinning at 0.2rpm(one rotation per 5min), id need more data from other people of the same comet at diferent(shorter) exposure times to compare the results and see if it worked
swan from a few nights ago. just figuring out the process 110x60sec
it's an artefact, ill fix it and come back
that's what i got and sadly there isn't anything usefull there, i was trying to use a trick that magnies any movment in a scene to see if the nucleus will show any signs of repetable oscilation in size or shape that could be a result of the rock inside slowly rotating and water jets that are coming off the comet could then affect the nucleus but there isn't any sign of that here so either those effects just do not occur or the image zoom needed is much higher to uncover them
that's where the comet is stabilised, there is some flickering around the comet but not at very repeatable intervals
the brightness of a comet doesnt actually mean how active the tail is, the two are usually related but clearly not now
Right, thing is I have always seen photos of the comet with super prominent tails
I guess that's with a bit of HDR process ๐
swan used to have a bright tail, then it got way further from the sun so it disappeared
Oh, that's not the ๐ one!
I am always so confused by there being multiple comets at once ๐
Might be interesting if only comet flickers and not anything else ๐ค
I'd be kinda surprised if you're able to determine the angular speed of the comet from the length of my subs and my pixel scale :oo
Tbh there were some clouds on that day, I have wayyyy better subs from last night that I can share if u want this instead? They are 90sec subs as opposed to 60sec subs before tho
i can give it a try but im afraid that what is needed is more detail in the nucleus from a more sensitive camera not a dlsr and more zoom
dslrs are plenty sensitive in the visible range
Fair, ask maybe @knotty crane
@lavish lark i missed my chance of imaging A6 from home. It doesnt rise to 30+ยฐ until 8am, when the Sun is out 
rippp
thats why you dont wait for comets to get bright folks
Some polar lights next to the comet as a bonus ๐ฎ
Comet is just a bit tiny at 50mm ๐
Now how the hell do I stack the comet in this horizon shot, I have no idea xD
OH THATS NICE
I MISS THE AURORA TOO
IF A METEOR SHOWER AND A COMET VISIBLE ON A NEW MOON WASNT ENOUGH
cloudy for you? :<
these clouds are gonna be the death of me
lemme just show you how bad it is
Beautiful
and it continues for uhhg
until the 23rd at least
I have a chance to catch stuff tomorrow night but after that im really out of luck
๐
I do plan to make the most of it
with my
terrible whatsapp camera (I have a good phone camera but it DOESNT WORK because it fell out of my pocket while I was tying my laces) and birdwatching binocs that picked up both a3 at mag 4 to 5 and 12p at mag 5.2
I should buy some binoculars for astro too ๐
Dad saw this comet as well trhough them, but very dim
bonus points if you can get one like mine that can record video n stuff
(how I got all my a3 pics)
digital binoculars ๐ฎ
I wasnt
i was waiting for a clear night
binoc vs phone camra
oh wait no I picked a bad video
better
looks like you got hundreds of little comets ๐
1st time catching A6 in the evening to the west this time. Not super ideal position, but I made it work. Ran the Rock'nOn 135 this time.
I am wondering which is the phone camera's work and which is the f/1.4 work, both are problematic... ๐
Niice, my goal is to resolve some nice tail structure like this too
That's not bad ๐ฎ
So those are birding binoculars which are sensitive enough for astro too, and they are not optical and fully digital?
โ๏ธ ๐ฆข
nice
yea
can do photos too but stuff shows up better on video
I see, cool
turns out it was cloudier than expected and I can't go for a6 tonight
my next possible chance is the 24th and if not then I'll probably miss the rest of the observation arc as well
whos?
Comer snapped :(
controller disconnected
What did it break apart
Ye
I have seen a great image from czechia that shows a similar structure
My framing is way too tight for this ๐
Woahhh what bortle is that??
Nice
Short and sweet.
18x 120s Lum
6x 60s ea RGB
Very nice
a6 activuties
Clouds
A6 likely peaking between 3rd and 4th magnitude. This week will likely provide the best views/captures of comet Lemmon.
Oh yes can't wait for the best views of the comet, ๐๐
Love it
what views
RIP to all yalls
rip to me as well
yeeeeeee
I had one evening to see it xD But there were polar lights and meteor shower too, so it was okay
enjoy 1 second crappy a6 video because the 14 second one is too big to send
wait I think discord compression merged the comet with the clouds lmfao
here's a screenrecpord of part of the 14 second one
a6 is the dim fuzzy patch in the bottom right
How do I watch orionids? Any tips
a simple 3 minute stack with a dslr and 50mm on a tripod
naked eye in a b8 is underwhelming
just a hint of the tail disconnect
niiice
Is this from the weekend? I saw in a monday photo that the tails are pointing different directions now
I've managed to capture Lemmon's cometary jets
From saturday! My goal was to have both tails visible, mission succesful 8D
hey
would any deep sky or comet person want to try and process my comet lemmon stack? ive got 0 expierence in deep sky detail extracking and i think my data has decent potential, if you do lemme know ill send the exported tiff, thanks
gween
Send it over I'll give it a shot
Want me to email it to you?
Just upload it to wetransfer or Google drive and share the link
anyone experienced with stacking comet lights files? ive been trying for days, following along tutorials etc, but i cant get a single good stack. Im still pretty new to this, but i managed to capture around 500 subs and around 400 in the same session.
what are you stacking in?
I tried Sirill, DSS, ASS4, Seti. But all gave me various (bad) results :/
are you going for a star trailed image or one where they're normal?
I tried both, also tried to follow along several tutorials for DSS and Sirill
I used deep sky stacker for the first time ever yesterday and it worked
DSS spits out a horrible result, the comet is more a line even after doing exactly as shown, and sirill gives me a bugged FIT. The light files are all alright, i checked them.
how many subs did you use?
You have to use Comet mode
would you mind sending the subs my way?
hold on imma dm you the google drive link, gonna upload them quick
cool
You need to use comet mode in dss
And manually locate the comet in each sub
Oh bruh
more probably makes it slightly more accurate but you just need an early sub and a late sub
I need to stick to planetary ๐ญ
currently uploading, around 400 subs. MAybe thats also too much?
tried it too, but the comet still is like a line, even after locating the comet in every single frame.
I don't think that would be all too big of a problem
did you remember to actually set it to stack on the comet
100000%, since i tried about 10x already :/ Its my first time stacking a comet, im prolly messing up somewhere
Liked you click the setting that says stack comet and not both or just stars
yep, even tho i also tried the both option once or twice, but the result was always the same sadly.
wack
ged fit?
what?
wdym by a bugged fit
when i crop it in sirill, it changes the stretch, gets horrible noisy and artifacts show up.
which arent there before cropping
sure, mind if i Dm you? i cant post photos here.
yeah no problem, forgot the image restriction was still in place 
@cursive elm protostar premium this gamer
zegery
gregory
please share the unedited stack, not the final PNG
Guys should I shoot the A6 with my roki 135 f2 and my asi 533mm or should I use my evostar 72 ed which is 430 mm in FL?
what bortle?
Shoot it with anything
I did this in B5
ill say 135mm
welp, idk what you did wrong but heres my stack of it
unless you like, didnt save it the comet position, i have no clue
autostretch
About 5/6 but I live literally 500meters from the beach where the comet sets so there should be way less LP. In fact last year when I images I think it was A3 I went to the beach and I could see it naked eye easily.
I would but I only have like one night or so
I did above
Here ya go
fellow west coast?
Def brighter tonight
is that an artifact to the bottom right of the core?
the changing color and tail is cool to see
Amazing! Do you by any chance also have a way to add the stars?
I live in Italy but yeah on the west part
c
Is that m51
holy
What's that meteor train, it's the second image I've seen of it
It's the vapor trail of a meteor.
Guys i got lucky, im shooting it rn
Is ๐ naked eye in Bortle 7?
no, i think a reasonable test for a6 visibility is if you can see andromeda
I didnt see it at all in bortle 4 so no
Damn you right. I'm getting it with the camera but no naked eye. Well, I won't complain.
should be easy in binoculars if you have any of those
this is so cool its like wrapping around it
https://www.facebook.com/share/p/1HxKxU9iv4/
here is the source i found later
See posts, photos and more on Facebook.
peaaaak
6min of data hence why It lacks colors shot at 50mm
so thats why a6 always looks white in my shoddy binoc videos
probably
ion captured enough a6 for it to a6 properly
Well you can see a slight very slight green color
ehh yeah I see it
I've had literally no time bc of clouds
that is just 6min of data lol
Shoot it through the clouds
i live in the uk
do you REALLY think that would be possible
I always wonder how much planes turn or if it's just perspecive playing tricks on me
Not my image but yeah, lots have clouds and they still make a shot. Never know what it's going to look like. Could be very interesting. Or not. But can only shoot for an hour or so... Not a huge time investment.
c/2025 k1 has returned from the sun and is now about 10th mag with bright tails. hopefully someone with a color cam images it soon
2 second exposures do look underwhelming but you can see it move
Oh wow
I donโt think itโs gonna look nice imaged from bortle 9๐ญ
It will look worse from bortle never imaged it.
^^^^^^
tic tac toe
yes ur right
it is??
when will it be the brightest actually
thats everything i got on the comet lemmon through the smog and bortle 9, about 12 minutes here
with my fma180 pro + p1 neptune 664c
I was rhyming lol
oh lol alr
here is a sub from a dslr with an 85mm lens on that was shooting at the same time with the main rig
there is a plane
my only image of c2023a3 has clouds but it has an insane backstory to it
god made a cool perspective here
That's fire tho
it is, and the best thing an astrophotograph could have is a story behind it
My A3 has a pretty cool story to go with it
visible from the north hemisphere?
yep
ooo
low in the east shortly before sunrise
how long will it stay visible? ๐
month give or take, but not that long while looking like this
these clouds better clear up istg
The weekend weather pattern of October 13th, 2024 was perfect and gave me the opportunity to try and capture the comet C/2023 A3. I was planning to travel to a dark site, but it was surrounded by low hills and mountains. I instead made a last-minute decision to travel to the top of a mountain in northern Nevada. At 8,200 feet above sea level, I figured this location would offer better visibility of a comet that was already very low on the horizon.
The decision paid off, presenting not just striking views of local visas but A3 Tushishan as well.
As dusk arrived, three generations of my family were blessed with the naked-eye visibility of comet C/2023 A3. As I was joined by my father and son, making it a true "once-in-a-lifetime" experience.
My humble cell phone capture that evening
wait you have a kid?
I have 3 ๐
i forget that some people here arent teenagers sometimes
or like, above the age of 25
I think the same thing when I go to a star party or outreach... I'm like whoooa, these guys are all retired lol
lol
that is beautiful man
thank you for sharing
I wish I had a wider lens but this was made that night at 270mm with 22 minutes of data
I'd done a couple previous but nothing of that magnitude
Got a small capture of ZTF and Mars which was kinda neat
missed ztf, and leonard, and nishimora or however its spelled
Same but was Halleys ๐
hey at least you have a half decent chance of a second go around for halley
True
Me at 28 ๐
old
young
Same here, I am apart of an astronomy club and almost everyone is above the age of 70 
Yeah
K1 has finally shown its true colors (lol), and I am stunned at how unusual it is
Even mono channels show that the gas tail is red
I don't think we've ever seen something like this so clearly before
Probably a comet very rich in sodium or something of that kind
maybe, iirc Mercury has sodium tail of a similar colour
Speaking of red. I had a botched data set where I was left with R and lum... So I ran as RLL.
a6 activitirs
I got both the comets, and K1 for some reason, never tried processing a comet so this will be fun
I suggest you try A6 first bcs K1's gas tail is pretty unusual
And smol
A6 is the best one in the pack, I could get nice structure in a preview shot
k1 thinks astronomy is a scam made vy telescope companies to sell more telescopes so its messing with us
https://cometary.org/@qicheng/statuses/01K8XJZGM72QF043GMK2HZPYC3 3I GOT RECOVERED AND ITS MAG 10
a6 activities
please ignore the stars and the fact that that is just 3min of data 
this is week is pretty much the last chance for northerners to get a good look at lemmon, about a week and a bit left.
I have one clear sky and a dream
i have chances at moderately clear skies, just enough height to see over the garage and a wish to catch it on the day of perehelion (8th)
I'm gonna try to photograph ๐ with my mak tonight. I'm crazy ๐คช
Nah, it's pretty bright. A mak would probably do good.
Initial reports coming in that R2 SWAN has fragmented. Still pending confirmation.
i broke it, sorry
stop destroying the environment
Yoy must be fun at parties(fr)
Hey, I've been to like, two parties and I was very fun there.
What yo ig

can it still be considered the environment if its outside Earth?
The universe is our environment
explodes comet with mind
Awesome stuff, always interested in these close up views, no one ever really did these, the only person to attempt this was from Peter ceravolo and his team in 1996 with hyakutake. I wish to do one like this, catching the dust tail jet streams and the ion tail like what you caught in that image. Great stuff
Still early in the detection phase but new comet candidate (identified as solar system object gb00810), detected November 2nd.
another comer spawned 
Those spawners are out of control with low light levels ๐
hey no torches we're in a comet drought
he says after getting 2 imageable comets in one month
we'll be out of a comet drought when we get another McNaught or two in the northern hemisphere
*6 this month
wait six??
ik 3i atlas, lemon and k1 but what the others
he says after g3, a6, k1, 3i atlas, r2, f2 etc
oh wait r2 swan as well
210p, 24p, swan, c/2025 t1
Man y'all have low standards
24p??
I'm talking Neowise and TsuchinshanโATLAS tier
g3:
even tho it hung around the sun it went crazy bright
a comet doesnt have to be naked eye to be cool photgraphically
Yeah but seeing a comet naked eye is undeniably cooler
true but naked eye only restricts your choices by a lot
What I mean is compare this century to the last one and we're behind on bright comets (especially in the northern hemisphere)
we're only a quarter of the way into this century ofc we'll be behind
That's after accounting for that
i mean, i think we're about on par
yeah I checked and only one great comet in the first 25 years of the 20th century (1910)
early 1900s had the great daylight comet, halley, and mellish, even accounting for me missing a few from that time there weren't all too many
weve had mcnaught, 2011 l4, lovejoy, neowise, a3, g3
ok yea that is a lot of southern comets
Maybe the 20th century had more than its fair share of spectacular comets (Ikeya-Seki, Hyakutake, HaleโBopp)
Kohoutek 
those 3 are later in the 20th century tho
1960s and after
kohoutek wasnt actually that horrible of a comet lol
it was just overhyped
probably like, comparable to neowise
yup (1910 and 1986)
It would have been a damn good comet for us imagers today
yep
lucky bastards
we only get halley once
damn you autocorrect
I remember attempting to see C/2011 L4 and failing
I had to type halley about 10 times
yea l4 kinda sucked
My first comet was Lovejoy, but not the sungrazer
i should've tried seeing l4 instead of being 2 ๐ฅ
I believe it was this one, I remember it being in Taurus when I saw it
i swear atlas just finds all of them now ๐ญ
tho this year was weird we had like 5
that weren't atlas
Soon every southern comet will have one name
Rubin
that's a lot of atlas
I also can't wait until we get GOES comets
what's thar
Well since SOHO is getting retired soon and we have a coronagraph on GOES-19, it's only a matter of time before it starts being the main source of sungrazer discoveries
c 2028 a2 goes (towards the sun)
from october 18th
im waiting for the punch comets
it has a wider coronagraph at a similar level of detail
YES
EXACTLY
thatโs what I want
Another mcnaught
I guess my essence has stayed until I came back
a6 perehelion today
What mag? ๐
idk theskylive keeps saying its dimmer than it actually is
and stellarium completely shit itself
telling me its mag 6
The Dutch say its 4.7 rn
bobs house
wjat?
4.6-4.7
Not worth imaging anymore imo, ion tail is just a straight line and the weather has been pissing me off
id say its worth imaging because its not coming back
if you havent got it already your basically doomed
Trust me, Itโs been said to me a thousand times, I will say it a thousand times; yes every comet is respectfully different from others but the key thing is we will have way better comets than this
yea but theyre in like, a while
Thatโs the thing, this whole hobby is a waiting game if you havenโt noticed yet
if you have the means to shoot a comet if you haven't shot it already, but you choose not too, thats just odd
Well of course I get that, Iโm a big comet guy, but things happen, I missed this whole thing because of crappy weather, if any chance I wouldโve captured it every night till itโs no longer visible
rip
speciall collectors edition
and?????
3l atlas looks so cool
not my image
why dont people use kappa sigma clipping here and leave satellite trails?
i think most scientific data has sigma clipping off
dunno
magbe to do with stacking soeed?
huh, it could aslo be to do with it could remove data
it looks like a sputtering flame
This might be a single sub considering how the stars aren't trailed.
just scooped a msm nomad advanced kit for 150$ usd, holy
now i just need another bright comet
no comet above mag 10 appears in you sky for the next 17 years
op
pa
the comets are there for everyone else it's just for you they're invisible
See this is why we canโt have nice things like comet mcnaught
normal a6 and a6 with larson-sekanina filter applied to show cometary jets
Awesome stuff, you can really see the what angle we have it at now
Date of capture?
25th of october
better one
k1, 20m in twilight
cute :3
next time you have clear you should shoot it
yea :(
It broke down ๐
is this comet aligned ?
it spit in 3
rip c 2025 k1
yes
triple actually
@delicate stone if u don't image this, you owe me ur newt
Looks like Iโm missing this one, gotta love November 
Cant even see it from my garden... fk that shit
Guess I'm getting a new scope!!!
When?
U can't even see it later on in the night?
Its cold and i cant stay up late
gosh I hate fog
not like tis gonna immediately disappear the moment it gets below 10th mag lol
people need to learn that its legal to shoot a comet past its prime, it'll probably be like 80% as cool
I remember shooting C/2023 A3 Tsuchinsan Atlas like below 10th mag and it still made me happy
Is the third fragment that spot in the middle?
yea
like between the other ones?
I can see lol
wish I knew about that fragmentation earlier but the weather doesn't do the job either
yea ive been neglecting this thread
well I'm not saying its your fault just to be clear 
3i ATLAS
smol
1050mm too
i shoulda ran the 10"
But..
got a huge cloud bank rolling in
its humid
and below freezing
a
disaster causing
Well try 3i again this morning
https://astro.vanbuitenen.nl/comet/2025R3
@lavish lark What u think of this one for next year?
bad
Because?
when its high enough to image it only reaches a max of 7th mag (assuming curent brightness trends hold up) with a northern maximum elongation of only 33 degrees at highest (translates to being about 14 degrees high at end of astrodark)
the 2nd magnitude peak is exclusively based on forward scattering, which for an object with an effectively unknown dust content is a risky bet
it also might disintegrate beforehand
best to wait then
at least its not too far away
what size and mag is 3i atlas right now?
i want to try it with my fma180 pro but i dunno if its worth it, will i get a tail?
Dimmer than 1-2 months ago at mag 12.4 but tail has a way better structure
that tail looked awesome on some images
Very but takes a lot of integration
a small bit of tail probably
Most of those images were with rasaโs
What was ur rig for this photo?
Askar 151PHQ with 2600mm
Yup. It's an exceptional copy at that.
I dunno if I should even bother imaging it with my fma180 pro and a 664c, I wanted to see a tail but looking at how itโs going I dunno
pretty dim these days
Yeah, if the core is that dim the tail must be even dimmer
I do have access to dark skies tho, bortle 4.5 towards the sea
Booo!
Is this C/2025 R3?
Ah yes i see it. Neat. Be fun to keep tabs and see if it survives it's trip.

how bright could it get?
Per the chart, below mag 0
that chart isnt very accurate since it isnt really based on a whole lot. no kruetz has been discovered this far out ever (theres only been 2 others that got discovered in the 21st century (on the ground)), so the error bars are massive
into the negatives, like -5. but that is dependent on so many factors that we have no clue about rn
that brightness will only be when its extremely near the sun in the sky, just a few degrees
that means it must be a big comet
no not really
what constellation is it in rn
I prefer to keep it safe in case it disappoints lol
yea, it'll suck for northerners anyway lol
it is 19th magnitude you are not catching it
it's definitely in the southern hemisphere, probably pretty far south right now
Kreutz sungrazers basically come from the south ecliptic pole
god we need a balance patch to fix the discrepancy between the southern and northern skies
trueeeeee
another C/2024 G3 possibly?
maybe, much closer to lovejoy
for a bit of context on how not known this comet is, the SOHO spacecraft has observed 5000 kruetz comets fall into the sun, of those, 2 have been observed from the ground in this century, comet lovejoy in 2011, and comet s1 atlas in october 2024. neither were discovered particularly far away from the sun, and s1 was a weird outlier
nerd!
:3
what does this mean about the new comet
Basically it means we have no clue on how bright it's going to get or how large it is
I suggest you check this post, it explains things really really well
I wonder shy is so many more comets visible better from south hemisphere - why do they prefer to come from one hemisphere more than the other? ๐
Kreutz sungrazers came from a larger parent comet that has a very southern orbit
Oh, they are fragments from a single large comet, that'd explain why it is so skewed ๐
you guys already have the good stuff why do you need our comets too ๐ญ
yall got milky way core, carina region, centaurus, lmc and smc, etc
Best we got is cygnus + rift and andromeda
(and triangulum but no1 cares abt triangulum)
I mean, tbf the comet might be acceptably visible around 20ยบ N
couldn't even make it out of the tropics ๐ฅ
at least we get 19p... in like 2028 ๐ญ
If I'm lucky I may head to the canaries and give it a shot if it survives
and i will be doing exams
And LDN1235 ๐คช
Sun grazers are usually southern hemisphere visible
R3 is also a sungrazer but now in the negatives
What is with the weird ass name for this new comet?
the sungrazer? its just the designation before it gets a normal name
idk why theyre called that
Officially called MAPS
If itโs bright enough we could see it in the daylight like mcnaught
Even the tail. My uncle saw the tail of McNaught on top of Haleakala over here on Maui
ah neat
Itโs perihilion is so close to the sun, itโs very likely it might not survive
But itโs now on van.buitenens website, -7.0
MINUS SEVEN????
and OF COURSE ITS CLOUDY
wait that s in april
still
right before exams season of all times??
Understand that itโs a sungrazer
-7 during perihilion
The orbit is so tight and so close to the sun that it will likely disintegrate but maybe would put up a good show before it does
Okay, I need to add some clarity with C/2026 A1
The thing is we have never observed a Kreutz Comet this far away
And they have suffered very unique conditions on their approaches to our solar system so we can't fully know how it's going to behave or how large it exactly is
Also, in case of survival, the peak brightness will last for considerably brief period of time, a few hours at most
Nonetheless, if the right conditions happen at the right time it could still be a pretty neat comet after perihelion
Also, I'd suggest a maximum northern latitude of around 25ยฐN
Any more north than that and it may be complicated to observe
C/2024 G3 was -5 at perihelion
More like -3/-4
visible during daytime at least
I only saw it on the SOHO images
I was pretty lucky, just focused on a distant olane and did a set of handheld images at approximately where I thought it would be
theres like 10 magnitudes of wiggle room don't get too hyped
mag -17?
vro
we have a sample size of 0
comets are already evil to predict, this comet is of a rare ish subtype, with little good data available on it
theres several levels of uncertainty here
nuh uhh, sample size of 1 :3
(current comet)
are they learing from this comded
@lavish lark what's the name of this comet?
c/2026 a1 MAPS
Tyy
diy coronagraph for this comet? thatd be a sick capture
Iโd say R3 panstarrs has a better chance of viewing than MAPS
It is a sun grazer but Iโm sure before that it is visible in the northern hemisphere on the horizon before sunrise
MAPS could be observed transitting the sun if youโre in the right location with a small few hour window. But Iโm pretty sure it will be fried by the time it wraps around
id say theres a solid chance of it surviving, but theres also a solid chance of it dying
not really knowable at this point in time
sad that r3 has a pretty horrible viewing window for northerners
No thereโs a great chance of it dying unless the comet is big, itโs 0.005AU at perihelion
Its orbit is super tight
its a kruetz though
could do something similar to lovejoy
I see, it is possible that the chunk from inside the Oort Cloud is big
?
Could be possible that the comet is big
If the tail is long enough I could see it from Hawaiโi before it wraps around
But Iโm guessing MAPS will be disintegrated by the time it heads its way back to the Oort Cloud
its not an oort cloud comet it has a 900 something year orbit
idk what that counts as
Whatโs your source? Most comets are typically from the Oort Cloud, from what Iโve heard they originate from the inside and a kreutz comet is stated to be a child from a big parent body that broke off
i suppose
i think that given the repeated fragmentation and extreme close passages to the sun, MAPS is not the same as a typical oort cloud object and shouldn't be labeled as such
Then where could it originate from
idk
*adjusted
What do you mean by repeated fragmentation
Are there any scientific papers stating the orbit? Because a 900 year orbit is very suitable for an Oort Cloud originated comet
A kreutz is labelled often as a fragment from a larger parent and a break off could result as an extreme pass
oh i was unaware of that
Anyhow Oort Cloud originated or not it still is an interesting one, maybe ISON potential
the progenitor fragmented, then the fragments fragmented
I see
What happens with kreutz comets is that most of them have already done several very close laps around the sun and have lost most of their volatiles
In fact they are thought too have less volatiles than the average dynamically old comet
So kreutz comets are completely different from what you are saying
They still break most of the time, but with the forces they suffer it's a certainty pretty much. Every single kreutz conet has fragmented at some point of their approach
What we have to hope for is that this one fragments or disintegrates at the right moment
yea pisces is just evil for us before sunrise
after sunset it's an absolute godsend tho
low ecliptic angle genuinely drives me insane
Well in that case, repeated fragmentation is strong evidence that it couldnโt be from the Oort Cloud
which comet are you talking about when you say "it"
maps
cool just making sure
But R3 before its perihilion should be fairly bright and visible to the northern hemisphere so Iโll be heading out to Bortle 3 for that one
I got hopes for this one, should reach close or in the negatives
r3?
Yeah
Mostly certain Iโd say
i mean a3 wasnt, and that seems to be a much dustier object that was also a bit more active
*actually wait a3 was imaged during daylight a few times
Comet C/2026 A1 (Maps)
C/2026 A1 (MAPS): Complete and live astronomy data, visibility information, sky charts, graphs, and tools for sky-watchers at all levels.
is it even posible to shoot it this close to the sun? from space yea but here the atmosphere will out shine it unless it's lie mag -6
Risk it at your own discretion
What is the magnitude of wierzchos???
imsohappy
c 2026 a1 perihelion during a school.hokiday for me
I can be able see it in the daytime although it should be too close
We are the official body that deals
with astrometric observations and orbits of minor planets (asteroids) and comets.
Potentially new interstellar comet
Eccentricity 1.77
observation arc is pretty short, most likely they just published a bad orbit
waitvwheres c 2026 b1
Looks to be down to .96 now? If I ca read the report correctly?
does it get bright?
i hope so
ok vanbuitenen still has the incorrect 1.77 dialed in
rip
apparently the original orbit had an eccentricity of SEVENTEEN
WHAT

February is teaming with new comet discoveries and good comets to view. In this no-nonsense video, we cover three comets that can be seen in binoculars to six-inch telescopes, report on the new Kreutz sungrazing comet, and what we know about the mysterious new comet found in SWAN images.
๐ญ What youโll find:
โข When and where to look for ...
Is this your channel by any chance?
no it isnt
Yeah, there are a ton of PGC in there.
Made another capture but I don't think conditions were as favorable
This lightcurve of Comet C/2026 A1 is bonkers.
what
Mag -40 ๐ญ we're abt to get a 2nd sun
sun is -26, nearby stars are getting incinerated
Safe to say clouds won't be an issue
you can image for once ๐ฉ๐
excuse me what ๐ญ
Yeah, COBS is very optimistic
we bout to be coocked alive
whole solar system getting flashbanged with ts
By the time of perihilion and Sun transit itโll be night for me on my end sadly
Diagram obviously unrealistic but itโll be in the negative magnitudes for less than a day Iโd say
If it reaches -3 or higher itโll be like seeing Venus in daylight which was fun to see naked eye
I hear that it'll likely not survive that long
Very likely, itโs perihilion is around 0.005 Au or closer Iโm too lazy to check but if itโs not big enough thereโs no chance of it surviving
matching its curve so far. interesting. I see captures are starting to come in showing a just a fuzzy green ball. Ill be keeping an eye on it and see if i can make a capture.
Man I cant edit it ๐
If you think it'll survive just use emojis ๐ธ ๐บ ๐ท ๐ผ ๐ฎ ๐ป ๐ช
-50 is criminal
that's like what
uhh
NEARLY TWO BILLION TIMES THE BRIGHTNESS OF THE SUN ๐ญ
-# i misread it as 18.5 billion instead of 1.85 billion lolll
specifically 1,850,120,435x as bright
there's like no way its going to happen
ikr what is cobs on bro ๐
its super optimistic
hell -10 is already optimistic
-50 is js wishful thinking atp
it would also fry the solar system
like all of it
mane shut up geminorum ๐ญ ๐
-7 is like a first quarter moon is it not
oh -7 is a 1% waxing crescent
-4 is like C/2024 G3 level but -7 would be mad impressive
I read on Wikipedia that it may be the second fragment of the original Krutzs sungrazer as it is big and its orbit matches with the 371 ad comet
That means really bright
Definitely not that big at all
Mightโve read it wrong then
Wikipedia is probably not a good place to check that stuff
It's almost definitely quite larger than lovejoy
But in no way it's a big subfragment of the 371BC comet
Those were pressumably the comets of 1106 and another one that went by in that same century
MAPS looks to be a rather mid-sized fragment
the hell did you do to the screenshot
When do you think the comet will desintegrate
7
18

I fear no gods, this rock will outshine THE SUN!
it perehelions in the middle of the day for me aswell
I am getting flashbanged
Potential ison?
I think its way too close to the sun
visible through solar filter?
I have no idea
one way to find out
Just dont remove it out of frustration 
Make makeshift soho with a throwaway camera and slow scope

maps!
R3 PANSTARRS shaping up to be a decent looker
*max mag of probably 4th when actually observable
Well see how it pans out. I'll be keeping an eye (lens) on it.
any captures so far?
i got it jan 31st
Super interesting that it matches the curve so far
currently its 1.15 au from the sun and comets tend to slow down the curve at around 1 to 1.2 au, so we're nearing the end
i cant recall a comet of similar orbit that maintained that high a slope to perihelion
I'd expect a outburst
?, you think one is happening now or one will happen
will happen
ig it could happen but its not like a garentee
not a "has to" happen
fair
hyperbolic asteroid
although i think that one is actually displaying minor cometary activity so its a misnomer
hmm okay
@lavish lark any norhtern hemi comets coming
maps is at 10th mag rn, odds seem pretty good for its survival
R3 has made a jump by the looks of it
sure has, recent image of it (not mine lol)
that tail looks nice
Whatโs up for this year. Any cool comets coming by at night?
This guy up there, and the sungrazer
Do you know if that was an outburst or just the result of missing data?
doesnt seem like an outburst to me, this comet is just brightening really quick
Its making a show for sure
this one
If one gets to mag -17. You might be able to spot it near the sun with a solar filter?
at least its not -50 anymore
odds are its getting to more like -8 absolute max
and -8 is insane already
so not solar filter visible
-8 is awesome. But yeah i doubt it will be visible
yea, more reasonable estimate is like -5 but nobody knows for sure
hell it could completely die and suck and only be -1
bro gonna outshine venus for a bit
yea
remember was it C/2025 S1
*2024 s1
that guy that disintegrated
yea
Looks like just an ion tail
probably because it is one
I was hoping for a nice dust tail but beggars canโt be choosers
it can develop one later at least like a6
that says -99
no, that's the perihelion date marked in red freaking out
rip
16 dyas unilt maps perihelio!
do you think its gonna survive
It looked tiny on some pictures i've seen
I think it could do a C/2024 S1 move
-8 would be visible by blocking the sun with a building
Sounds like C/2026 A1 MAPS is on its way to disintegration.
source?
Ah I thought you meant there were images of it falling apart already
that paper uses an outdated nucleus size and also ignores the fact that maps is a kruetz comet?!?
Yeah
The paper is well done but as bob said there are many variables that haven't been taken into account
First of all- maps was measured to be 400m wide by JWST
Ppl say it's smaller than lovejoy but I shall remind that lovejoy was NOT directly meassured like MAPS was, so I wouldn't be surprised if MAPS was still larger
In any case, yeah, kreutz comets are quite almost literally built different
If average comets are hard to predict, a kreutz comet is like playing bingo
They ARE much more resillient than the average comet though.
But anyway
For these guys it's a game of patience until it's at perihelion at this point
Literally survival of the fittest - all the weaker fragments have already been smoked by previous encounters with the sun
Thatโs logic though, smaller fragments are only a few meters wide
Sky & Telescope has a good graphic: https://skyandtelescope.org/astronomy-news/latest-news-on-kreutz-sungrazing-comet-c-2026-a1-maps/
Oh yea
Been following that guyโs research since tsuchinshan-atlas
Kreutz comets are much more of a mรญster y though
Because up until earlier this month, MAPS was brighter than usual due to many possible reasons- for one time we try understanding this family, we find an exception since this one has been around the sun one less time
Yeah, itโs full of surprises
yeah that jump is really notable
Oh the jump is typical
Iโm talking a bit more about the stalling lately
ah yeah
Kreutz comets should be more depleted of gas
So I hope thatโs why this one has stalled- because of having more volatiles than the rest of kreutz and losing most of them
Instead of something more catastrophic
like it spinning itself up and tearing apart before perihelion
But tbh finding patterns on these guys is almost impossible, so weโll have to wait until next week When It approaches The Sun at its fullest
Yup
Thatโs also What happened With C/2024 S1
Oh i thought it was just too small
So yeah, even without the one less orbit arguement they still go all around
Thatโs another possible reason
We canโt fully know
Both have been theorised
fair enough
MAPS looks much more stable visually, but we donโt know just how much
The stalls are weird
And just now Itโs gone down (brightened) a magnitude in like a day
Which could be finally the perihelion brightening or an outburst
Iโm kinda hoping images come in, but itโs getting harder and harder now
really difficult since it sits in the constellation Cetus
Yeah
Atp only southern scopes can handle it decently
Someone caught it in AZ but yea
o
I wonder if it's got a baked crust that's gonna split open and release a bunch of volatiles when it gets hot enough
Has anyone here found out what the reported issue is on C/2026 A1 Maps?
C/2025 R3 PANSTARS is looking pretty good with a loooong ion tail
yes, I've seen some nice pictures
conditions were pretty poor for me. Lum data only. ~45 minutes. 414mm fl
damn thats a lotta satellites
so bad. worst ive ever seen lol
single 180s lol
holy satellites
180s as in 180 satellites?
So if MAPS gives us an espectacle, will it only be after perihelion?
For northern hemisphere ppl after the 5th of April
I have a feeling it might break since it started to release gases all over the place
?
that horizontal line is from optics crap
No, have a look at the movie thingy
meow
that what ur talkin about?
Nooooo wait
look at the comet bru
the nucleus is not smooth, its releasing gases all over the place
a
@lavish lark say smart words
the oval bit?
yea
that is also a camera artifact from glare
https://ccor.nrl.navy.mil/realtime-movie this is a different newer spacecraft that doesnt have that artifact as much
its getting brighter (yay!) and getting closer to the pylon and doing wack ass diffraction things
i love diffraction :D
How did Lovejoy look at that distance?
Diffraction caused by the pylon
Yep
It looked quiye larger, but
We have ro take inro account that maps is somewhat behind the sun, while lovejoy was in front
Geometry caused significant forward scattering
Also since MAPS has approached when we are almost in the plane of the Kreutz orbit, its tail is more narrow
Neutralising Lovejoy's forward scattering, they are actually quite on-par
So its gonna swing around in front which is super interesting
Probably not at all
It will have lost its tail by then to begin with, and perihelion fading will make it unobservable
yeah it should lose its tail and then like get a new one
looking at it right now is nice
hard to determine the nucleus
fingers crossed it survives lol
Oh so i was not tripping that I literally saw it get smaller
can you give the source?
Looks rough
Our Best chances are that
- The comet detached from itโs tail early
- The occultation disk caused the fading
Still It doesnโt look too good. Iโd wait until like 6h from now perhaps, but yeahโฆ
I have a feeling it broke around that time or maybe its the diffraction again
Seeing those images Itโs very unclear
RAW files are more favored to the first, but idk
We'll see
shouldnt it briefly show up on the right side before swinging around again?
Nah, in case of survival it's already done that and it's too close.
Also perihelion fading would have made it impossible
Something emerged from the sun on the right side where the comet should be
Its visible in the CCOR craft
H u h
What timestamp does the exposure have
It cant be a flare or CME
Can't it?
Seeing the high quality video it really looks like the starter of a CME
And MAPS should be emerging from the other side anyway
I didnt see anything on the SOHO
