MDM Observatory 1.3m Telescope Observing Report for 2012 May 30

Observer(s): Emir Karamehmetoglu, Marcus Levine, Helena Uthas
Institution(s): Columbia

Instrument: Nellie

Worked for 9 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 1.8 arcsec, Clear, Winds Calm
   Mid: Seeing 2.3 arcsec, Clear, Winds Calm
   End: Seeing 1.6 arcsec, Clear, Winds Calm

Observing Summary:

There were intermittent oscillations during the run similar to last night, but it wasn't effecting the run 
too badly until about 4 am. The guider would no longer track/guide at this point. And the oscillations
made any further data obtaining impossible. This happened with the telescope close to zenith
and we moved to an object not near the zenith, (ring nebula,) just to check if the oscillations
went away; they did disappear. Otherwise conditions were good, and seeing drastically
improved when the moon went down.
