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.

For those of us in North America, this unfortunately happens before ISON rises. The closest we can see it will be about 1.8 degrees from Spica. Still it will be a nice pairing in a wide field instrument.

full moon


That may be true. But Spica is EASY during Full Moon, and with the current brightening the core should also be easy and have obvious movement, even over short observations.

Unless it's cloudy, it's worth a look.

I was able to spot Ison this morning just after 6:00 am even though the sky was hazy. Estimated mag was @ 3 or 4 and all I could really see was the nucleus and surrounding fluff like a globular because it was so hazy out.

I first saw it with a pair of 7x35 binocs, then at 35x with my 34mm ES 68 eyepiece in my 10 inch reflector. I then used my 9mm ES 100 at 133x to see the nucleus which was stellar.

No tail was seen at all because the skies were hazy, but I was really thrilled to have seen it at all! I'm going to keep looking for it every chance I get now.

I also got treated to a really nice view of Jupiter at 218x with my 5.5mm Meade 5000 WP UWA after that! I could have saw Mercury as well, but by that time, heavy, thick clouds rolled in.
