Comet C/2012 S1 ISON have companions?

January 16, 3 MB ..

Probably some kind of reflection but obviously animation shows 3-4 moving objects behind comet at same speed as ISON ..

I'm not expert on this but think is interesting enough to post here ..

I wouldn't start a rumor on that! Remember what happened last time!

Following the Heaven’s Gate suicides, the public learned that news of a “companion UFO” trailing Comet Hale-Bopp —

I did see what you are showing in that clip-weird!

Not seeing any objects, unless you're referring to the pixel things...


But given that these things that appear are EXACTLY *ONE* pixel in size.

Sharp as a tack, precisely one pixel, no more, no less, no blurring, constant brightness, etc... then they clearly arent actual objects being imaged with the telescope.
I'd say more to do with the actual imager itself, and only appear to "move" because the telescope was tracking the comet (although the video was made with the stars as reference).

Yap, "pixel things" ..

Thank you for more info about this ..

I see some "Hot" pixels but nothing following ISON.

BUT! I plan on following and photographing this comet as I am sure thousands of amateurs will be. So I am sure if there is something following someone will find it.

It is possible it is part of the comet broke off in the past to doesn't that make a little more sense than say...ALIENS?

Thanks I think?

I should have mentioned to that if I do capture something anomalous I will of course post it on ATS. But frankly I am just hoping for a great show from this comet got high expectations and since I was not about to see Comet McNaught 2007 (C/2006 P1), I would love to see one during the day!

I see a very bright pixel following the comet (to the left and slightly lower), dimming out of view for a couple of seconds and then appearing again but fainter. If it's just a dodgy pixel on the sensor, it would be strange that it follows the comet. There's also a smaller (fainter) pixel to the upper left of the bright one, following in the same direction.

I'll ask around on astronomy goups.

The hot pixel will follow the motion of the telescope, which in this case was probably tracking the comet over time (either autoguiding on it or through external software). When he then went and made the gif animation he registered the images relative to the stars, not to the comet, thus the hot pixels follow the comet. I sent Mr. Lawrence a tweet and asked him to confirm this, will post his reply if he replies; he's fairly well-known in the UK and I'm sure quite busy.

Ison may not have a companion now, but it will have soon though.
Comet Lemmon

At this rate of brightening, Comet Lemmon will likely be at least faintly observable to the unaided eye from mid February, for southern hemisphere observers, at the same time and vicinity as C/2011 L4 PANSTARRS

Southern Comets

We're all gonna die!

The first report I saw of this made a big deal about how this comet was likely a brand new one straight out of the oort cloud . In all honesty my first thought was ; I wonder if this thing got knocked loose by something ?

Goes without saying if it did there could be other things got knocked loose , not to mention possible fragmenting . I would say it's worth keeping an eye on but I think there's going to be plenty of eyes watching this thing .

Here is a better capture, and this italian astronomer actually said that ISON was chased by some asteroids

Yes, that image clearly shows asteroids, but the OP's image clearly shows hot pixels predominantly (there is one asteroid in there as well, but it's up and to the right of the comet near the top just right of center and is not visible the entire time - it fades out towards the middle of the animation, probably a thin layer of clouds came over as the stars fade too). One shows a point spread function (the asteroids) the others in the OP's do not. The one you posted was also taken a month prior to the OP's. Different part of the sky, different objects in the same field of view. It shows hot pixels as well which also moved with the motion of the telescope over time, but in your example the motion is vertical in the image and roughly perpendicular to the motion of solar system objects within the image including the comet and asteroids.

Incidentally, the photographer of OP's image, Pete Lawrence confirmed it was noise in the image (ie, hot pixels), and that the tracking drift of his telescope was coincidentally in the same direction as the comet over time.

"Pete Lawrence ‏@Avertedvision

@Vim_Fuego there was tracking drift between images and I suspect it was coincidentally similar to motion of comet. I can prove this later "

Here's a crop centered on the asteroid I found in the OP's image:

Based on some astrometry I ran on his image I have identified it as asteroid 2002 TY164, which was the closest asteroid to the comet in the sky that evening (not physically close though - the asteroid was about 3 times closer to earth than the comet but was itself still farther from us than the sun).

Thank you "ngchunter", thank you all for sharing more info about S1 ISON ..

From Jan 7, on this animation I can see one "object", "hot pixel" or asteroid in front of S1 ..

Interesting. Saw something else move along the same direction, but near the top-center of the picture. This is relatively bug, and is also followed by a hot pixel a a little further away to the left. Anyone else see this?

You mean in the OP picture? That's the asteroid I was pointing out, 2002 TY164.
