Observer(s): Thorstensen & Klusmeyer
Institution(s): Dartmouth,MDM

Instrument: OSMOS + B4k

Worked for 5 hours (first half of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

   Rain from 1 AM until 1:15.
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Seeing 1 arcsec, Patchy Clouds, Winds Moderate
   End: Patchy Clouds, Winds Light & Variable

Observing Summary:

Good usable conditions for the first half, with high cloud
coming over around midnight.  Parked telescope and closed mirror.
After about an hour we were surprised by a sudden rain squall,
and closed dome immediately, but not before a significant amount
of precip fell!  Tilted telescope over to allow water to run 
off mirror cover, and set up the big fan to help dry off.  
Did not open cover to check condition of mirror itself - hoping
little or no water got on the mirror, especially given that 
it was just washed. Remained closed later due to humidity.

Occasionally one gets taught to be a bit more conservative ... !
