(* means a trouble report has been issued or appended to)
1st half observing specialist: Karen Gloria
The telescope was opened at 17:30 MST.  Julianne Dalcanton was
observing remotely from UW.  We had intermittent network problems all
evening.  Most of these originated offsite.  The net problems cascaded
into problems with the cloud camera, problems with Julianne's SPIcam
connection, and occasional problems with the mc.  Julianne was a real
trooper through it all.
We had a lot of high clouds for the first part of the evening.  These
were accompanied by poor (2 - 3 arcsec) seeing.  The clouds eventually
departed and the seeing also improved to 1.5 - 2.0 arcsec.
2nd half observing specialist: Russet McMillan
The connection to UW hung twice during second half -- once around
00:10, and the second time around 04:25.  On the first occasion, the
tmcnode had to be restarted; it got stuck in the middle of a slew,
several minutes *after* the connection to UW had gone down.  The
second time, there was a freeze of a couple of minutes in the mc, but
it recovered.
The bias images from spicam were showing the old corduroy-type noise
pattern that has been seen before.
