                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Russet McMillan
 First half had widespread cirrus and good to moderate seeing. Everything
went smoothly.  I tried to record a representative cooling curve for SPIcam
so that we can eventually adjust the autofocus algorithms.
 2nd Half Observing Specialist: Noel Camron Hastings.
 Started out second half clear then a few clouds moved in. We switched to
DIS and during focus I found the pointing to be off by quite a bit. I made 2
corrections and this fixed things. Previously the program was observing at
very low altitude. Encoder errors looked good. Clouds moved in around 03:00
and forced us to close around 03:30. The clouds kept getting thicker, and
the humidity rose and rain was approaching on the radar, so we called it a
night around 05:00 MDT.

   note: the wind was coming from the azimuth listed.  The convention
   used is north=0 degrees, east=90 degrees.  The dust count is particles
   > 1u per 0.1 cubic feet.
