MDM Observatory 2.4m Telescope Observer's Report for 2008 Apr 27 Observer(s): Frank Institution(s): OSU Instrument: CCDS Worked for 9 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 1.5 arcsec, Cirrus, Winds Moderate Mid: Seeing 3 arcsec, Clear, Winds Light & Variable End: Seeing 3 arcsec, Cirrus, Winds Calm Observing Summary: Until 2.35am local time, everything lets me enjoy the better seeing, and then : prospero stalls on me. Had to stop observing with CCDS after numerous trials to remedy the situation (see touble report). Switched completely to retrocam which was completely unaffected, and observed the microlensing event for the last 1.5 hours. ------------------------------ Submitted on 2008 Apr 28 [5:58:23]
