MDM Observatory 2.4m Telescope Observer's Report for 2003 Sep 03

Observer(s): Fesen
Institution(s): Dartmouth

Instrument: ModSpec

Worked for 4 hours (first half of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Humidity from 11 pm until 5 am.
   Beg: Patchy Clouds, Winds Light & Variable
   Mid: Patchy Clouds, Winds Light & Variable
   End: Patchy Clouds, Winds Light & Variable

Observing Summary:

Night started out mostly clear but seeing wasn't very good.
At 10:30 pm LST, the humidity rose pass 85% and stayed there
for nearly the rest of the night. Clouds rolled in at midnight
to make a murky, high humidity night. (Oh boy, my favorite!)
As if it were planned, the sky largely cleared off at 5 am
(at astronomical twilight) along with a major drop in humidity.
Timing is everything...
