                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Barentine
 Poor weather precluded opening completely.  Brian used DIS to take some
cals early on; we switched to SPICam around 21:00 after all their DIS
targets were gone anyway, despite weather.
 2nd Half Observing Specialist: R. McMillan
 The snow started to stick on the ground after 22:00, so we ran the
 snow program for a few hours.  There was some partial clearing of the
 clouds after 03:00, but continued fog, blowing snow, and ice on the
 dome made it impossible to open.
