              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan,P.Gaulme
Cloudy first half, then a little bit of rain after midnight.  While the
dome was closed, we experimented with the secondary and got some more
information about the galil fault that was causing problems earlier in the
week.  We don't expect it to cause problems for normal observing, but we
do want to know more about the nature of the problem.
Then the weather turned good and we opened.  Seeing looked good, but we
did not measure it.
We did not recheck collimation because we only opened in the middle of
the night, but we did two pointing models and a corrected pointing.
The pointing in the altitude direction still needs a little bit of work.
The dark current on DIS appears to be completely resolved on the red side.
