MDM Observatory 2.4m Telescope Observer's Report for 2006 Mar 20

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

Instrument: Modspec + echelle CCD

Worked for 9 hours (most of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.2 arcsec, Cirrus, Winds Moderate
   Mid: Seeing 1.2 arcsec, Clear, Winds Moderate
   End: Seeing 1.2 arcsec, Clear, Winds Moderate

Observing Summary:

A very unpromising afternoon and evening turned good after dark -
by moonrise the weather was perfectly clear.  A tad windy, 
humidity rose for a while before dawn but receded before crossing
the limit.  Major incident of the night was the dewar failure 
at the 1.3m, but 2.4m behaved well.

Only one minor glitch -- an asynchronous read error from the 
CCD.  These seem to happen from time to time, rarely, so I didnt' 
bother filing a trouble report.

Spent a good bit of time revising the 2.4m User's Guide to
reflect the computer changes and the usefulness of GUI skycalc
(which now has the guide star selector integrated).
