                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Closed most of the night due to large amounts of wind blown snow.
 When we did open for a short while during second half the dis slitviewer
 was acting very perculiarly. It would display a blank frame (perhaps the
 mask only?) after every telescope offset. This would cause guiding to
 complain until a good frame would be taken the next image. restarting
 dcamera/dcam had no effect. I used the engineering time to setup a spicam
 filter wheel for tomorrow nights observations, I did a filter inventory
 of the 3.5m filter storage cabinet and I took some time to train myself
 how to run cormass. I also updated the idl on the FastcamPC and started
 looking at recent data.

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