MDM Observatory 1.3m Telescope Observer's Report for 2002 Mar 13

Observer(s): Eric Miller
Institution(s): Michigan

Instrument: Echelle

Worked for 6 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 1:00 until 5:00.
   Beg: Seeing 1.2 arcsec, Patchy Clouds, Winds Moderate
   Mid: Seeing 2.0 arcsec, Clear, Winds Calm
   End: Clear, Winds Light & Variable

Observing Summary:

First half of the night was non-photometric with thin stratus
clouds and low humidity.  At 1 am, the humidity monitor had 
reached 68% at the 1.3m (which is apparently inaccurate), so I 
called the 2.4, where the humidity reading was over 85%.  There 
was also condensation on the cars, so I shut down.  The humidity 
dropped quickly at 4:30, so I opened for the last part of the
night.
