MDM Observatory 1.3m Telescope Observer's Report for 2007 Jun 15 Observer(s): Vestergaard Institution(s): Arizona Instrument: ccds Worked for 8.75 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 2.0 arcsec, Cirrus, Winds Light & Variable Mid: Seeing 1.4 arcsec, Cirrus, Winds Light & Variable End: Seeing 1.3 arcsec, Clear, Winds Light & Variable Observing Summary: No problems. Had some cirrus to the west and northwest at sunset and later at midnight had more come in from the northeast, but none of it affected the observations (except for a slight fading during one exposure). Humidity went up when the cirrus came in from the NE - light beam was visible (even only at 20% humidity). Overall an otherwise great night. Seeing was relatively good. ------------------------------ Submitted on 2007 Jun 16 [4:47:16]
