                  ------------- ACTIVITY LOG --------------
   Observing Specialists: N.C.Hastings
     Dome was opened early to allow a German film crew to take shots of the
site, and we remained open to cool. Sky cleared nicely at sunset and all was
running smoothly. Craig worked on a minor bug in our 'gmonitor'.
     Seeing was extremely good first half. Switchover went smoothly.
Textbook observing all night.
