Minor planet 2005 YU55 is set to make a close flyby of Earth the evening of Tuesday 8 November. Closest approach occurs about 17:00 MST when it will be about 315,000 km out, mag ~11 and ripping across the sky at 515"/min. But at that time the Sun will have not quite set here in Utah. Fast forward to 22:00 MST and the sky will be dark but 2005 YU55 will be about 60 degrees above the SW horizon and still zipping along at a respectable 300"/min. Unfortunately the nearly full Moon will be about 40 degrees to the east. Hmmm, and I just noticed the remains of the recently broken up Comet Elenin will be about half way up the eastern sky. Now if only the weather will cooperate. patrick
