(* means a trouble report has been issued or appended to)
The telescope was not opened tonight due to poor weather (snow, fog,
and high winds) as well as snow already accumulated on the enclosure
roof.  At this time there is 2 -3 inches of new snow, a lot of
drifting, and it is snowing heavily.  Some drifts are waist deep.
The scheduled observers were Dan Zucker for UW13 and David Reiss for
UW01.
