                 ------------- ACTIVITY LOG --------------
                  Observing Specialist: Camron Hastings
   I opened at 18:00 MDT to begin cooling for about 20 mins before I had
to close for calibrations again. We opened again at 19:05 to focus. All
ran smoothly, no problems encountered with telescope.
   At 23:35 MDT or so the commercial internet connection died. There was
no interruption in observing with UW or Princeton due to the VBNS
connection remaining active. It appeared that something at NMSU was
messed up as 'traceroute' showed.
   Pointing was very good all night and clouds became thick around 02:00
MDT and just got worse from then on.
   We had a fire alarm in the new dorm at 04:44 MDT, but was a false
alarm. Dust went over the limit at 04:50 MDT in the enclosure despite the
fans being off an press fans on.
   Despite the weather, the Princeton team got good data. :)
