MDM Observatory 2.4m Telescope Observer's Report for 2006 Mar 18

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

Instrument: Modspec + echelle CCD

Worked for 5 hours (first half of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from 1 AM until dawn.
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Moderate
   Mid: Seeing 1.5 arcsec, Clear, Winds Light & Variable
   End: Fog/Low Clouds, Winds Moderate

Observing Summary:

Heavy cumuloid clouds all afternoon cleared off a little after
dark, leading to a stretch of quite decent conditions until 1 AM,
when the curtain came down abruptly with foglike low cloud and 
high humidity.  The good weather lasted long enough for me to get
a key high-airmass observation of the newly-discovered 
CV Swift 0732-13, thus resolving the ambiguities in its orbital 
period (it's 0.235 d).
