                  ------------- ACTIVITY LOG --------------
 First Half Observing Specialist: J. Dembicky
 Clouds prevented us from opening at twilight but clear enough for us to
 open at 18:55.  Dust and humidity were both borderline but the radar
 showed some clearing skies moving this direction.
 The dust counts hovered around 3000 to 3800 cts for the first half.
 Since they were not spiking and staying relatively constant I opted to
 keep the enclosure open.
 Second Half Observing Specialist: C. Hastings
 I closed at switchover when dust went over 4k, then humidity also rose
 over limits, so it seemed a good decision. When humidity and dust were
 just barely acceptable the clouds were opaque.

   used is north=0 degrees, east=90 degrees.  The dust count is particles
   > 1u per 0.1 cubic feet.
