                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 Opened for just a short while before cloudcover then humidity kept us
 closed for the remainder of the first half and the first 40 minutes of
 second half.
 Prior to focusing the telescope for second half a quick check of the
 collimation was done by taking an out of focus doughnut. The effect
 of the cateye mask was quite evident and nice. The central obstruction
 did seem slightly out of round but it was difficult to see if it was
 far from being placed centrally. Certainly some Shack Hartmann data is
 needed in the near future.
 The second half observer reported excellent seeing for exposures with spicam
 under 250s. For exposures longer than that trailing in the direction of
 tracking could be seen. This effect was very evident for a 600s exposure he
 took.

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