MDM Observatory 2.4m Telescope Observing Report for 2014 Dec 26 Observer(s): Halpern, Lucy Institution(s): Columbia Instrument: OSMOS 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 1.5 arcsec, Clear, Winds Moderate Mid: Seeing 1.3 arcsec, Clear, Winds Moderate End: Seeing 1.1 arcsec, Clear, Winds Moderate Observing Summary: A very clear night. Did simultaneous spectroscopy with time series on the 1.3m. The only problem was that twice during the night the OSMOS slit wheel timed out because the IE lost communication with it. We followed the clear troubleshooting procedure in the OSMOS User's Manual to recover. ------------------------------ Submitted on 2014 Dec 27 [7:02:22]
