Seeing and Weather: Beg: Seeing <~2 arcsec, Clear, Winds Light & Variable Mid: Seeing 1.5 arcsec, Clear, Winds Calm, T_out < T_mirror End: Seeing 3-4 arcsec, Clear, Winds Calm Observing Summary: At midnight the head electronics suddenly wasn't responding. It took me several hours to get it back up. Details in trouble-report. By then the air-temperature had dropped below the mirror temperature and for the rest of the night the seeing was pretty bad (3-4 arcsecs). Ugh! ------------------------------ Submitted on 2002 May 21 [5:21:34]
