(* means a trouble report has been issued or appended to)
The telescope was not opened tonight, due to winter weather (what
happened to spring?).  The site received about 3 inches of wet snow
during the day.  Most of that melted in the afternoon.  Flurries and
fog most of the night, then clear followed by wind and snow.
The utility power was out at the site for about an hour this afternoon
while the electric coop worked on a problem at the Sacramento
sub-station.  We ran on generator power during the outage.  A hose
popped off one of the pumps for the primary mirror support system this
evening.  I fixed it and it popped off again later.  Now there may be
a problem with that pump, so the PMSS will need to be worked on today.
