                ------------- ACTIVITY LOG --------------
 Observing Specialist: Russet McMillan
The night started out mostly clear, with good seeing, but storms began
to threaten around midnight and the telescope was closed at 23:45.
After a few sprinkles, we continued to watch the clouds and lightning
until it appeared safe to open at 03:15.  Both programs were able to
get a fair amount of data, and there were no unusual problems aside
from some difficulties in getting DIMM started up.
