                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Clouds and humidity kept us closed until around 22:30 when the humidity
 dropped below the clousure limits.
 Nancy did a time swap with Don York for tonights first half for DD time
 on 04/01/05 that had been promised to  her.  I recorded her time ad UC06
 (Don's program, but Russet may want to  edit this to a DD time, since the
 DD time swap is for the next qtr.).

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
     Note: The Tower Dust counter appears to be down at this time
