Yes it will "roll over" with the tail pointing further north each night over the next week as it moves ahead of the sun on your horizon

Finally had my *first* look at PanSTARRS last evening. After 3 unsuccessful attempts the weather finally improved enough. On March 15.73UT I estimated it at magnitude 1.7, but the estimate is quite uncertain due to unfavourable conditions. I could see it easily with the naked eye with the Sun at -9. In 20x110B it looked very nice, a classic comet with a very condensed pseudonucleus, parabolic coma and gently curving dust tail. An impressive sight in large binoculars, but (very) far from a Great comet. It resembles C/2002 V1 (NEAT) back in Feb 2003 at a similar elongation (and heliocentric distance), although it is somewhat brighter.

Nice sketch, Larry--very well done. It looks like pastels or conte' on grey paper?

Jure, glad you got to see it--thanks for the detailed report.

Here`s my contribution to the thread, certainly not a wall hanger but Phil Creed, Tom Kiehl and i was able to get our first view of the comet last Thursday.
You can see what we deal with here in Ohio on a nightly basis.

No ^

Spaceweather.com has a photo of Panstarrs with a "chunk" below it following the same trajectory. Possibly BREAKING UP?

This was the view from Dallas on March 13th around 8PM.

770mm focal length f/7 and 2.5s shutter. The image is copped to about 0.5 degrees square. The two stars in the frame are about 8th magnitude, HIP 2510 and HIP 2659.

The comet was brilliant through the scope and through 10x50 binoculars. The comet was just barely visible with naked eye. Or maybe I convinced myself that I could make it out, not exactly sure which, with averted vision I thought it was there a couple of times.

I've just returned from my 4th attempt to observe Pan-STARRS
Clear skies except for a vital 7 degree high bank of clouds over the Pennine Hills - so FAIL

Anyway - I've finished my first image from my only sucessful night - 13th March

In Zagreb we had clear but frosty night with temperatures hovering around 0C and less. Comet was first spotted on live view image on camera screen around 18:40. After that we trained our binoculars and telescopes to comet and there it was, small bright disc with two faint tails. I took few pictures and went home cause I coulnd't feel my fingers any more, they were frozen

Here are two images of the comet

I finally got to have a good, if quick, view of PanSTARRS. I have to mention that it was easily visible naked eye last night, during an evening of good transparency. A stubby tail was on and off visible with averted vision, but with 15x70 binoculars it was magnificent. I hope for better viewing tonight...

Panstarrs - March 17, 2013, 0121 UT. 400mm, F/5.6.

I went out at sunset on March 16, 2013 to my spot I've been viewing and imaging Comet Panstarrs from. Got a chance to use my 5.5 inch Comet Catcher and a 15mm Expanse eyepiece on it. In addition to the nicely condensed pseudo-nucleus, I detected like a filament of brightness in the tail structure starting at the central condensation and curving in a slight arc away from it. I had to look in between clouds and controlling my camera, since I was also shooting the comet. The photo shoot results are above. There's also an 8MB animated GIF image I made with 76 frames, if you want to see it moving.

The image above is a base 4-sec image, the comet parts of 4 other 4-sec images and 15 other 2-sec images. I did what I could to make it half-presentable. Lots of clouds in my shots. I could have totally scratched and not got anything, so Im pretty happy with this one despite the clouds getting into my pics. Plus, I am really happy to have seen the comet through something bigger than my binoculars.

Howdy all;

I had lots of fun at the Messier Marathon last night. I saw Comet Panstarrs in modest binoculars and in Paul Lind's 14 incher. John Rhodes, the Televue rep, imaged it in a TV 101 and for short exposures there were three nuclei seen. You had to zoom in the image, but they were there. Anyone else see this? It was not seen visually, I saw it as having an elongated core, but not seperate pieces. If I remember, John said he shot 3 or 5 second exposures.

Clear skies;
Steve Coe
