              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Thin clouds for most of the night, but good seeing.  For a short period
during second half the clouds were bad enough to prevent observations, but
mostly we were able to shoot through them.  Once again peaceful and
productive.
