Comet ISON Appears Near Spica - Nov 18
Posted by Centaur on Thursday, November 14, 2013 11:12 AM
Comet C/2012 S1 (ISON) will appear geocentrically to pass the first magnitude star Spica by 18 arcminutes on 2013 NOV 18 at 03:52 UT. Below is my graphical representation of that conjunction.

Thanks, Curt:

I've been trying for a week now to find ISON in 15x70 binos without any luck.  Hopefully your charts will help me nail it down.

Chris,

Comet ISON has just brightened significantly (see my recent post) so you should have a good shot at seeing it.

I hope so, I've been trying every morning around 5:30 - 5:45AM.  I thought I may have seen it once yesterday, but could not confirm it even to myself.  Definitely no tail spotted.  Being so close to Spica on Monday morning should definitely help out.

Unfortunately, the Moon will be full then.

True.  But so near to dawn it should be pretty much out of the way.  Morning twilight may be a much bigger problem.

Bang Head Wouldn't you know it!  ISON "blooms" to a much brighter magnitude and I get up to a pea soup fog in our area... Go figure... Crying

I was outside this morning before 5:00 a.m. EST and was able to see Comet Lovejoy easily enough through my 15x70s from my backyard, despite a brightening sky.  

A bit later I walked down the block to a spot with a better eastern view but was unable to sweep up Comet ISON.  There was some low-level haze.  I could see Mars, Porrima, and Arcturus well enough but Spica was in the trees.  Comet ISON was situated between Porrima (Gamma Virginis) and Spica at the time.  I called it quits a bit after 5:30 a.m. EST.
