                ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Dembicky
 High dust, high wind, clouds, and humidity kept us closed all night.
 Never opened the mirror covers on the telescope, dust levels reached
 about 5K inside the dome with the press fans on.  The humidity most
 likely kept them from actually running which explains the elevated
 inside dust levels.
 With conditions near or over closure conditions, and cloudy skies to
 boot, we gave up and called it a night at 04:25.
