                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Started the cooling fans around 16:00.  Opened the enclosure/telescope at
 17:05 under clearing cirrus skies.
 Seeing went way south around 22:00 jumping between 1.5-2.5 arc sec.  By
 23:00 we were lucky to get 3 arc sec with it bouncing between 3-4 arc
 sec.  Sloan reported that they were seeing similiar conditions with
 their telescope.
 We switched over to GrIm at 00:10 and the seeing had improved to about 1
 arc sec in J when we focused.
 Everything ran smoothly tonight.
