                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Dembicky
 Opened the enclosure around 16:30 to start cooling.  Got on the sky at
 sunset. There were a couple minor NIC-FPS ICS problems (or confusions
 from an error that came thru) around 18:10 when I went to focus.  Nothing
 serious and I had the telescope focused around 18:25 with 0.7 arc sec
 seeing in J. A couple other minor computer glitches (like filling up the
 disk on /export/images with all the Data the NIC-FPS can produce!).
 Nothing big and only very minor science time lost, nothing notable.
 NIC-FPS was fairly well behaved tonight with lots of data taken.
 2nd Half Observing Specialist: Russet McMillan
 Second half had varying high clouds.  We remained open the whole
 morning, but some of the time it wasn't even worth opening the
 instrument shutter.  Everything worked smoothly.

     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
