MDM Observatory 2.4m Telescope Observing Report for 2012 Dec 07 Observer(s): James Runge, Jacob Brown, Marat Musin Institution(s): University of Missorui Instrument: OSMOS Worked for 14 hours (all night) Conditions were Non-Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Seeing 1.3 arcsec, Cirrus, Winds Calm Mid: Seeing 1.3 arcsec, Clear, Winds Calm End: Seeing 1.2 arcsec, Clear, Winds Calm Observing Summary: Noticed a lack of tracking when moving between targets, did pointing everytime we moved to a new target in order to mitigate this problem. Lost synch with Calaban/IC after aborting an exposure. Problem solved after a reboot of IC, lost 1.5 hrs of observation. Prospero GUI missing some images after restart, does not interfere with data acquisition. ------------------------------ Submitted on 2012 Dec 8 [7:23:36] NOTE: This report replaces the previous 2.4m telescope observing report for 2012 Dec 07
