                ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Dembicky
 We had a Tunderhead form to our W/NW at sunset and moved over top of us
 during the first half.  We used some of the time to do some closed dome
 test of the Az reversal and magna-sensor errors.
 Clouds for most of the night.  We did get onsky for about 1 hr.  Just
 enough time to focus Fastcam but we didn't get to aligning it before the
 clouds came back.  We also had a broken fiber that shut us down at the
 end.
