This comet in Pegasus is getting much brighter than predicted. So check it out!

Jef,

Excellent observation and sketch. I've read that the comet has a very condensed stellar-like nucleus and your sketch shows that very well.

Jef,

It looks great in your sketch.
The last time I checked it was rated at about magnitude 12.4, does that seem about right or do you think it is brighter?
I can't check here it is cloudy now.

Jef

Thank you so much for informing about this comet. Tonight the sky is clear and I have the same SQM as you. I'm just back from my dome and I found the comet. Pretty one with a small tail like on your beautiful and precise sketch.

Thanks.

Andre.

A link in the Planetary group brought me here,

I was able to observe tonight from Tucson with Instruments from 60MM to 250MM. Based on Stars in the vicinity I would estimate the Comet at around Mag 11. The Nucleus is small and bright, so smaller instruments (100MM or so) might have a hard time resolving.

Movement was evident after circa 5 minutes.

Sky was 3 of 5 as clouds were approaching, and closed down by 9:30 local time.

Excellent sketch, and thanks for the heads up. I was in pegasus friday night, but didn't realize this was around now.

Thanks! Good luck in your own hunting.

I'm not really a comet specialist and didn't estimate the brightness. I was already very happy in seeing one after a so long time! But he was surely brighter than 12.4 (otherwise I would have a very hard time in seeing it with my SQM 19.1).

Yes, 15 minutes before I placed the comet on the sketch he was on the same "level" than the two stars to the left.

Nice sketch. I imaged Hergenrother last evening (10/6) and to me it looks like it could be close to 9th magnitude. Thanks for the view.

I like your sketch Jef. I checked this one out last night in my 8" SCT and it was much brighter than I expected! Thanks for the tip, I think I'll keep an eye on this one for a while.

Lovely sketch, thanks for sharing. That will get me motivated to see if I can find it in my 8" dob.

Thanks to you all. I hope the comet will stay bright for a long period because it's a nice little thing.

Nice sketch, Jef.

I hope to see it grow brighter, so that I can take a look with my binoculars as well.

Erika and Rony: thanks!

@ Rony: I heard from observations with a 15x80, so give it a try.
