A nice sucker hole opened up tonight and I seized the opportunity to try and catch a glimpse of this jewel. After about 5 minutes of searching with no luck, the sucker hole was beginning to close. I could see the cloud bank getting closer to Orion. Tick Tock Tick Tock. As good luck and bad luck would have it, I found it about 20 seconds AFTER the cloud bank covered it up with a thin layer. The view would come and go but I never got a good clear look at it, although I could tell it was definitely a comet. I could see it even with the thin cloud layer and all. Better than nothing I guess. I hope I can get a good look at it before it's too late. Darn clouds.

Hi Everyone,
I've been off the boards for a month and when I looked at this thread there were 104 unread posts! Some great sketches, images, and observations which I just got caught up on.
My last observation of C/2012 K5 was November 22nd when it was in Bootes with almost daily solid cloud cover since then so when it cleared off the evening of the 7th (8th UT), I was anxious to get another look at the comet. By now it was in Taurus very near Aldebaran.
I was surprised how bright it was. My GoTo is a little off and put the comet core just outside the field of view but I could see the glow of the coma on the edge of the FOV.
The tail wasn't uniformly diffuse--it appeared to have streamers in it.
As others have noted, this is a fast mover--probably the fastest I have ever observed. I placed the comet just below the center of the FOV so I could include the tail in my sketch and in a half hour it had moved completely out of view.
@ Mike Phillips--you must have imaged the comet shortly after I sketched it. The starfield behind the comet trailing behind the tail to the left is the starfield in my sketch.
I'll tell you what people--it's getting crowded up there in space. A meteor went through my FOV during this observation followed shortly thereafter by a satellite.
Best to all,

Continuing clouds in north central UK are still preventing me observing since 01/02 Jan 2013. I'm probably going to loose it now in the Leeds city (intense) glow to my south. So next up - 30 month PhD report and then ..... PANSTARRS ...

Sorry to hear that you are not getting any clear nights. Not too many here either as it has been a warm cloudy and wet winter in the PNW.
Here is a calibrated image stack of the comet taken on 02 January. Unfortunately I forgot to take some guided star field subs so the stars are trailing in this stack. But it was nice to see that SH 2-235, a faint nebula, was just in the frame which makes for a nice contrast subject for the comet.

Another clear night with almost no moon tonight.
Here is a bit over 2 hours same procedure as earlier- 30 frames per second/30 second exposures. I had to stretch quite a bit more. Magnitude has dropped significantly.

Here is my stacked data.
Also captured some ISON tonight, but I'm ready for bed.

PJ, nice catch on the comet.
John, very cool video--the comet is really zipping along.
Tony, good luck winding up your PhD--we'll keep an eye on things for you while you are otherwise occupied.

Thanks for the appreciation Special Ed. I must say your sketch is a very good observational capture of the comet. Thanks for posting your effort for us to appreciate.
On 02 January SkyTools reported a comet motion of 12.9 arc seconds per minute and on 10 Jan a motion of 6.34 arc seconds per minute. It was really moving along!
Attached is probably my last image of the comet due to it moving rapidly lower in altitude and the continual cloudy night skies. It is 22 X 3 minutes guided on the comet taken on the 10th of January.
Cheers
PJ

Impressive image. K5's tail has a definite curve to it, thanks for the view.

John / RLYTS thanks for the thumbs up on my latest image.
As this one heads out I guess it is on to the next one - PANNSTARS then ISON. Hopefully their expected brightness will give us more of a visual sky show !
Cheers

Go to the PANSTARRS thread for latest brightness predictions and links to graphs - no longer a great comet candidate

PJ,
Thanks for the compliment on my sketch. The latest images by you and John W are quite nice--that curving dust tail is something to see!
With Luna making her presence known and K5 fading, I guess I'm done with this comet--only two observations.
