                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st & 2nd shift: Noel Camron Hastings
    Opened at 19:30 to begin cooling. Started on time, good seeing, good
weather. The guider did exhibit the same shutter sticking problem that
was seen last night. A problem report was submitted then, so I did not
submit another. Tracking and pointing were very good tonight.
    Second half started on time, clouds began to show up. UW's SPIcam
program ran without trouble. The guider shutter sticking seemed to
disappear. The night's events seem to again suggest that it is a heat
related problem.
        ---------------  OBSERVER'S COMMENTS  ----------------
J.Dalcanton (UW05): Lovely night, excellent seeing, expert help.  Guider
much improved over the spring runs -- very little degradation between 10
second and 10 minute exposures -- kudos to the engineering squad.
