Weather Report for April 29, 2012

At the start of the night there were some very light cirrus and decaying contrails to the northwest. The sky quickly cleared and a bright, first quarter moon made it easy to see that the sky was clean for most of the night. Seeing typically varied between 1.4 and 2 arcsec. Overall, a good night, but the moon was bright enough to prevent faint targets from being observed during the first half of the night.
