MDM Observatory 2.4m Telescope Observer's Report for 2003 Aug 27

Observer(s): Jules Halpern
Institution(s): Columbia U

Instrument: Echelle CCD Direct

Worked for 1.0 hours (last half of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from start until 01:00.
   Beg: Overcast, Winds Light & Variable
   Mid: Patchy Clouds, Winds Light & Variable
   End: Clear, Winds Light & Variable

Observing Summary:

For the first time this semester, conditions became suitable
for observing at 01:30 hrs.  First collimated the 1.3m primary.
Then used the 2.4m long enough to establish pointing and
and rough focus.  Humidity rose again at 03:15 and I closed up.
No science data obtained.

Noticed a drop of condensation in the middle of the CCD
dewar window (see Ximtool window on Chichon monitor #2).
Presumably this will evaporate or be cleared with dry nitrogen.
