                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Dembicky
 Opened the enclosure and started cooling around 16:15 tonight.  Seeing
 was poor at around 1.7 arc sec and clouds moved in around 20:00.
 We had some clearer skies move in from the East around 23:20.  After
 waiting to make sure it wasn't just a sucker hole (we had 3 systems
 moving in 3 directions over us) I opened back up around 23:55.  I
 focused the telescope at 00:07 with 1.5 arc sec seeing and handed the
 telescope back over to the observer.  The wind went above closure limits
 around 00:55 and kept us closed, as well as humidity later in the night,
 the remainder of the night.
