MDM Observatory 2.4m Telescope Observing Report for 2009 Feb 04

Observer(s): R. Mark Wagner
Institution(s): Ohio State University/LBT

Instrument: CCDS

Worked for 5.5 hours (first half of the night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 0.8 arcsec, Clear, Winds Calm
   Mid: Seeing 0.8 arcsec, Clear, Winds Light & Variable
   End: Clear, Winds Calm

Observing Summary:

Completed science and CCDS throughput measurements for all the
gratings that are currently in cells.  In addition, I measured
grating zero order encoder zeropoints for all the gratings as
well.  THis should make it easier to set up gratings for use in
CCDS.  Thanks to the MDM staff for their excellent support.

TIFKAM can go on the 2.4 m Thursday. I did not refill the 
CCDS dewar in the morning.
