                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Barentine
 Opened again at 19:40 under mostly cloudy skies, yet with no imminent
threat of rain.  That all changed at about 21:00 when the rain sensor
alarm tripped unexpectedly.  We opened again as the sky cleared toward
21:30.  Skies cleared progressively until around 01:00 when cirrus began
rolling in from the southwest.  The cirrus was supplanted by thicker,
spotty clouds around 02:30.  After finishing his exposure and taking some
calibrations, George decided to give up for the night.  Between that time
and the start of Lens observations, I took an Echelle spectrum of a long
period variable I'm following.
 Scattered clouds in the south and east prevented running the Lens program
as scheduled.

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