                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st & 2nd Shift: Noel Camron Hastings
    I opened the dome late due to cloudy weather at 20:12 MST. I used a
few minutes to test the new slit imager focus work I did through the
thick cirrus. We then tried to get a standard, which was successful, but
right then the cirrus thickened up and we had to close again at 21:40
MST.
    The slit imager focus was off quite a bit so I worked on it this
afternoon and evening. The few on sky tests I obtained showed the DIS
cameras and the slit imager within about 10 units of one another in
focus, which is as good as we can ever expect. Collimators and slit
imager now working as a team again.
    Due to the full shift night (16 hours) and the poor weather, I
decided to close up shop early. The satellite showed no hope, and the
cloud camera was black for hours. I left DIS mounted for the next night's
observing.

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