              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had clear skies all night but poor to awful seeing.  APOLLO struggled pitifully against the bad seeing, getting no more photons than Count Count could handle.  Observations for the second program were more successful since the targets were extended, but the observer had internet trouble and so ended up observing more or less by phone.  During second half conditions were marginally better, but humidity rose as the morning progressed and by twilight it was pretty close to the limit.
