MDM Observatory 2.4m Telescope Observing Report for 2010 May 11 Observer(s): Ruhland, Gultekin Institution(s): MPIA, University of Michigan Instrument: CCDS Worked for 8 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 2 arcsec, Clear, Winds Moderate Mid: Seeing 2 arcsec, Cirrus, Winds Light & Variable End: Seeing 2 arcsec, Clear, Winds Calm Observing Summary: We observed a couple of BHB stars in the Milky Way halo. Weather was mostly good, some cirrus clouds at times. We had a problem with the display of the rotator angle which went suddenly to huge numbers while rotating. Problem got solved by rotating back (jumped back to normal numbers). It was not happening again for the rest of the night. ------------------------------ Submitted on 2010 May 12 [4:53:06]
