MDM Observatory 2.4m Telescope Observing Report for 2010 Dec 14 Observer(s): S.Lepine Institution(s): AMNH Instrument: Direct + Echelle Worked for 13 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 0.9 arcsec, Clear, Winds Light & Variable Mid: Seeing 0.9 arcsec, Clear, Winds Light & Variable End: Seeing 0.9 arcsec, Clear, Winds Light & Variable Observing Summary: Another excellent night. No clouds, just a little wind, good seeing. Fearing this could be the last perfectly clear night of the run, I switched to a backup program to characterize new nearby white dwarfs, which requires photometric conditions. Got UBVRI sequences of 37 targets. ------------------------------ Submitted on 2010 Dec 15 [8:04:31]
