MDM Observatory 2.4m Telescope Observer's Report for 2007 Feb 22

Observer(s): Marshall
Institution(s): OSU

Instrument: CCDS

Worked for 12 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 2 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 2 arcsec, Clear, Winds Moderate
   End: Seeing 2 arcsec, Clear, Winds Light & Variable

Observing Summary:

Bad seeing and wind shake all night.

Problem with CCDS acqcam focus--when the star is in focus in CCDS,
it is very far out of focus on the slitviewer.  This makes 
focusing the telescope during the night very difficult.

Over the last few nights, the dome has lost its pointing by up to 
40 degrees during the night.  It did not happen every night, 
but observers should be aware that it is a problem and 
to keep an eye on it.
