                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Started cooling around 18:00 tonight under partly cloudy, and a bit
 threatening, skies.  My observer started her cals with DIS around
 19:05 and the clouds moved off to the W around 07:30 and we opened
 then for science.  The guider died as I was trying to focus it.  Craig
 determined that it was a loose cable on the back of the guider Mac in the
 computer room.
 The clouds moved in around 22:25 and within 10 mins the rain sensor
 triggered.  I was just about to close the mirror covers when it tripped
 so I flew up the stairs and had the covers closed before too many
 sprinkles fell.  It was a very light and sparse mist when I went out to
 close the cloud camera after I had the 3.5m closed up.  I don't think
 much, if any got, on the primary mirror when I checked at shutdown.
 Clouds and rain, off and on, for the remainder of the night kept us
 closed.
