                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
    I opened the dome to start cooling at 16:15 MST today before the
observer arrived for calibrations. We then closed for cals and reopened.
I noticed that one of the PMSS desiccators is pink on the intermediate
level and in need of recharging.
    Today I tried to open DIMM and run the cobwebs out of it since it has
sat for a long time. I found the telescope stored with the lens pointing
straight up (good dust collector!) and the power supply dead. The laptop
was running, but the power pack for the telescope appears to have failed.
I will try and troubleshoot it when I have more time, but may need a new
power converter.
    The NMSU 1.0m dome had a failure that kept one shutter from closing.
I went up to check it out and found a few set screws on a clutch shaft
loose and tightened them up allow them to operate tonight.
 Observing Specialist, 2nd Shift: Russet McMillan
 Second half was very peaceful.  Despite persistent high clouds and
 variable seeing (ranging from 0.8-1.8 on the guider), many targets
 were observed.

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