MDM Observatory 2.4m Telescope Observing Report for 2010 Mar 20 Observer(s): Gaudi, van Saders, Shappee Institution(s): OSU Instrument: CCDS Worked for 8 hours (off and on through the 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, Clear, Winds Moderate Mid: Seeing 2.0 arcsec, Clear, Winds Moderate End: Seeing 0.8 arcsec, Clear, Winds Moderate Observing Summary: Beginning of the night went fairly smoothly. The seeing wasn't great, but we got some observations of a few supernovae. The wind was moderate (up to 20 mph) We then ran into problems with the dome, which are described in the trouble report. We spent several hours trying to solve this, but ultimately failed. We then decided to just observe and move the dome manually. Naturally, the seeing was excellent at this point (0.8 ). ------------------------------ Submitted on 2010 Mar 21 [6:16:44]
