                ------------- ACTIVITY LOG --------------
 2nd Half Observing Specialist: Russet McMillan
 The dome was covered in ice and snow and could not be opened, but the
 weather was not usable in any case.  Despite a period of clear skies
 after midnight, the humidity was high for most of the night, with
 some freezing fog.  The only dip in humidity coincided with returning
 clouds, which brought some very light snowfall.
