                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was not opened tonight, due to poor weather (some wet
snow and a lot of fog).  We received about 3 inches of snow overnight.
Current snowfall is 1 in/hr so total accumulation may be rather more
than that.
The observers were Mark Marley for NM03 and Bernadette Rodgers for
UW05.
