(* means a trouble report has been issued or appended to)
1st half observing specialist: Loomis
We are having a snowstorm here, with very high winds and low
visibility.  Santa will have a hard time finding Apache Point
Observatory tonight.  We've had gusts over 50 mph all afternoon and
evening.  No chance of observing tonight.
There is snow getting into the 2.5-m enclosure, under the bottom and
over the top of the east door.  There was a dusting of snow on the
cover on the front of the telescope and snow underneath the
telescope.  I've swept up the snow and stuffed rags up against the
bottom of the door.  A little snow is also getting into the 3.5-m
enclosure, around the door to the catwalk and also a little on the
east side of the intermediate level.
Frank and I took turns doing site snow removal, but had to give up
after a while due to the high winds.
I've advised Russet not to try coming in in tonight.  Frank is staying
the night.
2nd half observing specialist: McMillan
