MDM Observatory 1.3m Telescope Observing Report for 2011 Jan 17

Observer(s): S. Lepine
Institution(s): AMNH

Instrument: MkIII + Wilbur

Worked for 8 hours (last half of the night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Clear, Winds Calm
   Mid: Seeing 2.0 arcsec, Clear, Winds Moderate
   End: Seeing 2.0 arcsec, Clear, Winds Moderate

Observing Summary:

Started late on the 1.3m, after spending some time training
Jackie on the 2.4m. Telescope was opened and observations 
started around 11pm. Resumed the spectroscopic follow-up 
program of bright M stars. Conditions were windy, and there 
was some N-S jitter in the telescope.

It appears that the vacuum was lost in the dewar, probably due
to filling it up late in the evening. I noticed when the chip 
started heating up only 7 hours after the dewar had been 
filled. Dewar had to be re-filled again.
