                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 We opened under clear skies tonight.  I tweaked the pointing since my
 observer was going to be offsetting to targets that might not be visible
 (or near bright objects that would flood the chip with a long exposrue).
 Seein was excellent at the start of the night (0.8 arc sec or better on
 the guider), but then the humidity started to rise and the seeing became
 very variable (1-2.5+ arc sec).  I monitored focus with the guider all
 night.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
