              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear skies all night, very good seeing first half and moderate seeing
second half.  APOLLO got excellent returns.  Everything worked well except
for a small mystery concerning image transfer: when the PU05 observer
first started taking cals  before sunset, only the red ones were
transferred even though both red and blue were exposed and saved to disk
here.  He restarted TUI and the problem resolved.
