              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear skies and excellent seeing for most of the night; the seeing for the
first focus measurement doesn't look that good because it was right at
sunset, but it settled quickly after that.
We had trouble with the Agile rotator on the first move which would have
taken it to -165.  The observer preferred to work around the problem
rather than doing a longer investigation, so we just changed rotations and
only had a few minutes' delay.
