Tracking Interstellar Comet Borisov

that looks big

tRACKING MANY EXTRA-STELLAR COMETS?

hi.
Yeah, that's funny.

Haha that's what my hook ups always say....couldn't resist sorry

Is it slowing down yet?

If you have no interest in astronomy then take that giant forehead to another thread.

Are all those white dots in the second photo stars or noise?

Just random noise in the camera. This comet was around magnitude 16~17 and is the dimmest comet I have ever detected. I'm amazed I pulled out a hint of a tail in the image.

Tracking an inter-stellar comet has its challenges. Good work Dr. Astro

Nope. The raw stacked image data is right here:

Very cool.

Beautiful ! Thank you.

Go away, snake

Is anyone else doing this? Like universities with huge equipment? Seems like you are doing all the heavy lifting for the astronomy community.

Another Elenin ... sigh

thank you astro

Pretty cool

Sure, Hubble took images of it and of course captured much more detail and much higher resolution images than anything I can achieve.

This thread got much less attention than it would have normally.

Perplexing...

Did it change speed like the last one?

I haven't measured the coordinates of it astrometrically yet, but if I collect more observations later this month I can compare my results and see if there are noticeable amounts of non-gravitational acceleration. This one is clearly a comet, so I would expect it to exhibit that due to outgassing. The previous was one was not so obvious and much more... mysterious.

I wonder how many probes this interstellar traveler will release when it's on close approach to Earth. I possibly detected at least one last time.

Can you make an educated guess as to AU distance currently?

Where is the follow up, Astro?
Today is the big day. Today is Borisov's perihelion.
Will it survive it or break up as Ison did?
I find it strange that it being only the second interestelar comet ever seen in human history there is not much more public interest on it as there was with Ison.
I remember Ison's perihelion being shown in various live transmissions.
Why such little beeing shown this time?
Where is your telescope now Astro? We need it.

I want 3xplanation on dark artifact lines in photo 2.artifacts should be homogenous.lines means mirror/lens grinding defect or chip defect.

So are we going to be able to see if this thing broke up and its trajectory after it passes the sun? This is going down today, right? Thanks for tracking this by the way. Hard to get any info. Cannot see anything on SOHO.

Where is Borisov, did it broke up , is it still intact, did it brighten up?
What's going on?
First ever interestelar comet known to mankind and no-one is following it??!!
Where are the news??
