                   ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: W.Ketzeback
 Clouds were too thick until 2300 to open. I started ventilating around 2000
 when it looked like the humidity was going to stay below the limit.
 2nd half Observing Specialist: J.Dembicky
 Clouds were off and on thru the time we were open.  The threat from the
 East became too great, and we finally lost the image on the slitviewer
 around 02:10 and I decided to close.  Around 03:10 the rain sensor went
 off although precip was very light.  Humidity rose as well and that was
 what kept us closed for the remainder of the night.  We gave up around
 04:30.
