YALO Telescope Observer's Report for 2001 May 20 Observer: Juan Espinoza Observed for only a few hours from 22:48 to 01:40 UTC. Conditions were Mixed most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.8 arcsec, Clear, Winds High, surprize cirrus... Mid: Overcast, Winds High End: Overcast, Winds High Observing Summary: Stranger was the night... Because of strong winds and south moving clouds, I chose to go with photometric program at the start of the night. Bad choice. Clouds decided to turn around and settle above us for the rest of the night with no chance for releif. Needless to say, NoNPhotometric program was also unachievable. Photometric data taken tonight is about 80% good as time allowed. cheers ------------------------------ Submitted by Juan Espinoza on 2001 May 21 [4:45:10]
