                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Dembicky
 I started cooling the enclosure around 19:30 (enclosure fans only) with
 the threat of rain looming overhead and to the E.  As the humidity rose
 around 21:00 I closed the louvers and turned off the fans.
 Rain, wind and clouds for the better part of the night.  I finally decide
it may be safe to open around 03:30, just in time for the clouds to decend
again on APO.  We remained open, although conditions were extremely
marginal and the seeing was rather poor.
The PU03 program time was given to UC01 since the seeing was so poor.
