Comet C/2012 K5 is ready for chasing new
      #5519074 - 11/14/12 05:13 AM

If you want a comet to chase then its time to switch to C/2012 K5 (LINEAR) as Hergenrother fades away - from now and next month its brightening fast - peaking possibly near mag 8 on New Years day. For the last four weeks it has been tracking slowly over the shoulder of Bootes while turning to line up with Ursa Major. It will soon track through the Big Dipper/Plough tracing a path from the tip of the great bear's tail to the tip of it's nose.

However it initially favours those in the far north best as its extremely low or even set for most of the night for those at lower latitudes during November and the early/mid period of December. Right now its in the process of switching from a predominantly evening object to a morning object.

During the last few days of December and all of January its all-night visibility vastly improves as it rapidly races through Lynx, Auriga, Taurus and the Orion/Eridanus border before slowing to a crawl again and turning east under Orion.

Thanks, Tonk.

I'll start looking for it. Any kind of structure or tail visible yet?

Trying several mornings already to catch him for a first observation, but still bad weather. Anyway, my applet with comet positions on a simulated night sky is also extended with this comet C/2012 K5, also showing which deepsky objects shall stand close to it, there are some interesting ones. Hopefully an easy target this new comet!

I've created a display of the orbits of the Earth and C/2012 K5 as viewed from far north of the ecliptic and an ephemeris. They can be seen at www.CurtRenz.com/comets

Got my first look at C/2012 K5 (LINEAR) this morning. It took a while for Bootes to rise above the mountain to my NE so I didn't have much time to look before the sky began to lighten. The zodiacal light was very prominent this morning too--glad the comet is not over in that part of the sky.

I first picked it up at 75x--not real bright but definitely not hard to spot (especially with dark, transparent skies).

The comet is pretty well condensed with a fan shaped tail. Hopefully this one will be fun to chase--thanks for the heads up Tony and thanks also to Curt for the charts.

Here's the sketch:

Nice sketch! That looks really promising as a photographic target, too. My NE is dominated by LP, unfortunately.

Excellent observation.

I have been wanting to capture this comet but just can't seem to get myself out of bed early in the morning since its turning colder.

Very nice sketch. Looks like it may be a pretty good comet to track. Well done.

Thanks for posting your observation and sketch. Well done.
Weather has been its usual with storm after storm rolling
in off the Pacific so no opportunity to get up early and
view this fuzz ball.

Cheers

PJ

Mike, SteelStar, PJ, thanks! Hope you all get a chance soon.

I read a report on the Yahoo comet obs group that this comet's tail was at position angle 20. I put it at PA 340. One of us is confused--not sure who.

340 would have been about right. Position angle is measured counterclockwise from celestial north. Your Yahoo source may have mistakenly measured clockwise, or perhaps meant -20 which is equivalent to +340.

I've been imaging this comet for the last month (in its now near gone evening slot) - nice fan tail and yes it is noticibly brighter now

Thanks for the confirmation, Curt. My source posted another more recent observation with the PA of the tail at 350. He was using an SCT and might have forgotten he had a mirror-reversed view. More likely, I checked back and his observation was 10 days before mine and the PA might have shifted over that time. His more recent obs was the same date as mine and we are within 10 and both to the west.

Sorry no - I'm making an effort to get the data but I've too little time to go through the processing steps though. I'm currently under the whip from my PhD supervisors so I have to deliberately avoid distractions . I could slap up a rough "straight from camera" if you just want to have a look. Hopefully Mike B will do the honors with his efforts as I know he will turn his sights to this one soon

Sounds like you're keeping your nose to the grindstone. Good that you have some early data to compare to the comet's appearance later on when you have more time to process it.

I managed to get a 8 30 second subs on the morning of the
26th just before sunrise. the comet has a good defined
nucleus and a bit of a tail showing. The star to the right
of the comet is magnitude 12.7 Hopefully darker skies in
a week or two will allow a another attempt.

Cheers

PJ
