MDM Observatory 2.4m Telescope Observing Report for 2015 Nov 11 Observer(s): Ryan Chornock Institution(s): Ohio University Instrument: OSMOS/R Worked for 13 hours (all night) Conditions were Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Seeing 1.5 arcsec, Clear, Winds Moderate Mid: Seeing 2-2.5 arcsec, Clear, Winds Moderate End: Seeing 1.5 arcsec, Clear, Winds Moderate Observing Summary: Tonight was a queue night with OSMOS/R. I observed some targets for me and some for the ASASSN team. Conditions were clear and cold, but the seeing started off mediocre and got worse until a reprieve in morning. It was reasonably windy, with 15-20 mph avg wind speed for most of the night. There were various small things that cost me time along the way, including some files not being written to disk and the rotator ceasing to rotate (see trouble report). ------------------------------ Submitted on 2015 Nov 12 [7:28:30]
