MDM Observatory 2.4m Telescope Observer's Report for 2006 May 16

Observer(s): Sebastien Lepine
Institution(s): AMNH

Instrument: Direct + echelle

Worked for 3 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 all night.
   Beg: Overcast, Winds Moderate, dust
   Mid: Seeing 1.6 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.1 arcsec, Patchy Clouds, Winds Calm

Observing Summary:

Threatening clouds at sunset gradually dissipated
in the evening. However the wind also carried a 
lot of fine particulates (probably dust) which cleared 
up only after midnight. I resumed observations around
12:30AM, imaging 4 parallax targets under relatively 
good seeing but also the occasional cirrus. Denser
cloud cover put an end to observations around 4:00AM.
