For the Northern Hemisphere, Biver suggested the last week of January, when the comet passes between the Ursa Minor and Ursa Major constellations.
Has anyone seen this thing yet?
I was out before 0600 this morning with my binoculars. Ursa Major was clear, low in the sky to the North. I'm not certain where Ursa Minor is at the moment, anyway I couldn't see any comets.
