          1st & 2nd Half Observing Specialist: Jack Dembicky
 Turned on enclosure fans at 17:30.  Louvers opened at 19:25. Opened
 enclosure at 19:30.
 Scattered cirrus clouds at sunset which increased an hour afterwards.
 Seeing was variable and ranged from 1.1 - 1.8 arc sec for most of

 adjusted if necessary.  Most of the night it was fairly stable.
 Everything ran smoothly tonight.
