MDM Observatory 2.4m Telescope Observer's Report for 2006 Jan 25

Observer(s): John Thorstensen
Institution(s): Dartmouth

Instrument: Modspec + echelle CCD

Worked for 12 hours (most of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from 19:00 until 21:00.
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Moderate
   Mid: Seeing 1 arcsec, Clear, Winds Light & Variable
   End: Seeing 1 arcsec, Clear, Winds Calm

Observing Summary:

A good night, no problems.  Mediocre seeing and intermittent cloud
at start, one hour-long cloudy interval in the evening, then 
clear and increasingly calm.  Humidity was a concern but never got
too high.  

This is my first run since the new roller was put in the mount. 
It is a dramatic improvement -- the tracking never gave any 
problems at all, which hardly ever was the case before the 
roller was replaced.  That long-standing problem appears to have
been fixed.
