MDM Observatory 2.4m Telescope Observer's Report for 2005 Jan 22

Observer(s): Chris Morgan
Institution(s): The Ohio State University

Instrument: RETROCAM - MODSPEC

Worked for 6 hours (off and on through the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Humidity from 2000 until 0100.
   Beg: Seeing 1.0 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Clear, Winds Calm
   End: Seeing 1.0 arcsec, Patchy Clouds, Winds Moderate

Observing Summary:

Partially cloudy skies and humidity hovering in the 80-90% region made for a very inefficient night.  
I opened up for one hour before midnight and five hours after midnight. 
Seeing was excellent: ~1.0 arcsec (when I had the dome open and there weren't clouds in the way).
I observed three lensed quasars, fixed the RETROCAM lensed quasar guide star selection routine and measued the focus offset between MODSPEC and RETROCAM.
