I had some clear weather this morning so I took a peek at 05:30 UT. This comet is shaping up, estimate a 10' fan tail and bright nucleus around mag 8 to 9 ish. Prelimiary images show greenish small coma. Nearly overhead at onset of twilight at 07:00. Cresent moon, Venus and Mercury low to SE were fantastic too. Worth getting up for!

Yeah thats exactly how my prelim images look - even the green coma

Your trees must surround you as the comet is direct overhead just before dawn!

I had a good look at it last night with a 20" f/4 Dob at 80x under rather poor SQM 21.0 skies. The comet was still at only about 15 altitude and inside a light dome, but a very condensed coma and a curved fan tail, about 10' long were easily visible. It would certainly have looked much better later in the night at a higher elevation, but still, quite an impressive sight. Had 11x70 and 20x110 binos ready, but after 6 hours in -13 C and 50 cm of snow I wasn't too keen on waiting for another 2-3 hours
Clear skies!
Jure

Took this image of C/2012 K5 on the 19th with the Slooh Remote Observatory.

Tried to see it with an 8 inch Dob at 5AM and didn't see anything. It must be pretty diffuse.

Quite the opposite - its quite condensed and bright - are you sure you looked in the right place?

Best viewing location if the skies are clear: The Seattle-Vancouver area where the magnitude +8.0 comet will be in the zenith when it makes its closest approach to the Earth's surface at 0.2937 AU on 2012 DEC 31 at 00:20 PST. The ideal spot is W 124.94 - N 48.42 which is in the Pacific Ocean about seven miles west of the northwest corner of Washington State at the US-Canadian border.

Found it in my 8 tonight when it was around 20 to 24 degrees off the horizon. Difficult to spot. Not much coma. Condensed is definitely the word to use, but not bright. Tail was short and mainly visible with averted vision or a shimmy of the scope. I'm assuming things will improve significantly as it progresses. Was not easy comet to pick off and certainly didn't have the same kind of presence I observed with Hergenrother or Garradd.

I'll be checking back in on this one to see how things change.

Hi,

As Tonk said..its bright and easy to find, it looks elongated but couldnt detect any tail, as when we observed it on the morning of 16th this month...the sky wasnt very clear with the thin cloud cover sailing over getting views inbetween. It was near alioth and hence made for an easy hop. will try again before the moon moves in..

Hoping that it may prove useful to some I am attaching a map that will give a rough idea of where the comet will be the next few days..

Clear Skies!

Lo and behold, I located it from my driveway last night with my 15-inch truss-tube Dob. It showed a short tail, but between the moon still lighting up the sky at midnight and a streetlight right across from my house, it was not much to look at. At least it was recognizable as a comet.

I finally observed this comet last night using my trusty ST120 refractor.

I first found it about a degree and a half (below) from the star Dubhe at about 11:30 pm with a 70% waxing gibbous Moon high in the sky.

I got a little sleep and went back out and found it again about 2:30 am after the Moon had went down.

The comet was visible with low power but not my 9 x 50 finder. This comet seemed small to me and maybe had a brighter nucleus with adverted vision. A faint fan shaped tail was visible with hints of being longer than was obvious. At 11:30 pm it formed a nice triangle with a pair of stars and after about 3 hours when I came back out it had moved about 23 arc/min up next to a 9.4 mag star. When I defocused this star to about the size as the comet it was about the same mag.

Hopefully I will get my 12" dob on it soon. Sketch is flipped to match refractor view and shows movement between my two observing times.

If we get some clear skies here, I can try to bag this comet!

Observed it again tonight through better skies and when it was higher up near the meridian, definitely looks different than how it was last week...the denser brighter elongation appears less condensed now, more spread out really..and could see the tail flared downwards(as it appeared in the eyepiece). Not as bright as M81 nearby tho larger in size but much brighter than M51.

Clear Skies!

Well, I finally got a chance to see it this morning. Transparency and seeing were mediocre but I could see the big dipper so I went for it. It was easy to spot and I could see a faint tail. It was only 50 arcminutes from Dubhe. 85x was best.
