MDM Observatory 2.4m Telescope Observing Report for 2011 Jan 06 Observer(s): Shields Institution(s): Ohio University Instrument: OSMOS Worked for 10 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.4 arcsec, Cirrus, Winds Light & Variable Mid: Seeing 1.3 arcsec, Cirrus, Winds Light & Variable End: Seeing 1.0 arcsec, Cirrus, Winds Light & Variable Observing Summary: Successful night of observing quasars with OSMOS. At the start of the night I learned after some confusion that John Thorstensen's excellent osctrtask can appear to work correctly if run from the wrong directory but isn't really doing so. After that all went smoothly. Cirrus much of the night, occasionally rather thick. ------------------------------ Submitted on 2011 Jan 7 [6:15:50]
