                ------------- ACTIVITY LOG --------------
1st half Observing Specialist: G.Saurage
Clear skies all first half. The outside dust counter stopped reporting
data at around 18:00 (the enclosure still reported data). Jon Brinkman was
here and able to look into the problem and get it working again. Seeing
was fairly good tonight but variable.
2nd half Observing Specialist: R.McMillan
Second half was clear with good seeing.  Everything worked well,
including the DIS slitviewer shutter.
