              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds during afternoon checkout but a bit of a clearing (we still had high cirrus) at sunset allowed us to open and get some photons for a few hours.  By 21:20 it was again pretty cloudy.  I could not see any stars visually and my observer also was having difficulties with his IR sources.  I left the dome open until around 23:30, when we were pretty well socked in with clouds.  We didn't get anything useful after 21:15, so that's when I maked the finish time.
We had a thinning of clouds around 03:40 and I decided to re-open for the last program.
Mike finished a little early (05:45) due to clouds and spent the remainder of the time doing dome cals.
