                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st shift: Camron Hastings
    Rain and cloud kept us closed again. A hole appeared overhead, but
lightning all around, so I remained closed.
 Observing Specialist, 2nd shift: Russet McMillan
Clearing progressed after midnight, but we watched the progress of a
storm complex until 01:00 to be sure that it wasn't heading our way.
The telescope was opened just in time for the second half program to
proceed normally.  Clouds began to reappear around 02:30, but not
thick enough to prevent us from observing several targets.
The telescope and instrument were generally well behaved, except for
some previously-known problems such as the guider's inability to deal
with clouds.

used is north=0 degrees, east=90 degrees.  The dust count is particles
