MDM Observatory 2.4m Telescope Observing Report for 2010 Jun 04 Observer(s): Bird Institution(s): OSU Instrument: OSMOS Worked for 8 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.3 arcsec, Cirrus, Winds Light & Variable Mid: Seeing 1.2 arcsec, Cirrus, Winds Light & Variable End: Seeing 1.1 arcsec, Clear, Winds Light & Variable Observing Summary: Observing went smoothly last night. OSMOS behaved admirably. Still scattered cirrus and thicker stuff on the horizon but all in all, not bad! It was quite warm at the beginning of the night and then cooled off (so focus changed). Seeing settled down to 1.1 . ------------------------------ Submitted on 2010 Jun 5 [16:58:58]
