              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
Photometric with generally good seeing, except when pointing into a
lively north wind.  A crash of the slitviewer controller cost a few
minutes of time during the first program, but everything else worked
well.
The first half observers ended a little early so I was able to check
collimation with Agile, which looked just fine.
