MDM Observatory 2.4m Telescope Observing Report for 2010 Sep 10 Observer(s): Schroeder` Institution(s): Columbia Instrument: Echelle Worked for 11 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 1.0 arcsec, Clear, Winds Calm Mid: Seeing 1.0 arcsec, Clear, Winds Calm End: Seeing 0.8 arcsec, Clear, Winds Calm Observing Summary: I had some problems with the pointing tonight. Lost about three hours of data because I failed to check to see that the target was acquired since it was working so well the previous nights (assumptions should never be made!) Eventually, I had to reset the encoders at Zenith and slew to a nearby star which was totally off the chip to the South. ------------------------------ Submitted on 2010 Sep 11 [16:35:59]
