              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
High cirrus getting steadily thicker throughout first half, then high
humidity second half.  APOLLO got some weak signal but gave up early when
the clouds thickened.  Although the dome stayed open until after 2 am, the
first half observer was unable to get data part of the time and the second
half observer got nothing useful.
