I observed Comet ISON (C/2012 S1) for the first time with 10x50 binoculars. It is much brighter than I expected, slightly brighter than HIP62421 (magnitude 6.2), north of which it is just passing . It is almost as bright as Chi Virginis (magnitude 4.6) to its west. This is much brighter than predicted by Starry Night (magnitude 8.2). I thought I could just see a faint tail to the northwest with averted vision. This is very promising! While it is not yet visible naked eye, it is getting close to it.

Temperature =  0.8°C
