I predict that magnitude +9.3 Comet C/2012 K5 (LINEAR) geocentrically will appear to pass magnitude +1.7 Elnath (Beta Tauri) by 39 arcminutes at J2000.0 position angle 302° on 2013 JAN 04 at 23:57 UT. For Chicago observers the figures will be 38 arcminutes at 17:56 CST.

Below is my related J2000.0 geocentric graphic for the conjunction. More of my comet graphics and data can be found at www.CurtRenz.com/comets

Awesome, I'm really hoping to catch this comet for the first time tomorrow night(unless it clears up here early tonight). This should make it a bit easier to find. Thanks!

I just saw it with my 8" f/5 Newtonian. It's quite easy even through the light
pollution here (Chicago suburbs). It's actually clear. And cold. And windy.

Attached is a more detailed chart.

This comet is really moving. In the last hour it has moved noticeably relative
to the field stars.

Centaur,

Thanks for the heads up on this. I'll be looking for the comet tonight.
