MDM Observatory 2.4m Telescope Observer's Report for 2001 Jun 30

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

Instrument: modspec+echelle

Worked for 8 hours (all night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing 1 arcsec, Clear, Winds Moderate
   Mid: Seeing 0.8 arcsec, Patchy Clouds, Winds Light & Variable
   End: Seeing 0.8 arcsec, Patchy Clouds, Winds Calm

Observing Summary:

Another partly cloudy night, luckily with rather long clear
intervals.  Stopped work for about half an hour around midnight
when clouds got particularly thick.  Seeing, however, was 
good to excellent, which compensated some for the cloud and 
bright moon (81 percent illuminated at midnight).  No trouble
with the equipment -- again ran on generator.  CV period work;
given that I have but one more night it was lucky I was able to
plug some gaps in the power spectra.
