(* means a trouble report has been issued or appended to)
1st half observing specialist: Russet McMillan
Prior to sunset, Russ Owen and Craig Loomis tested a new version of
the TCC control software.  The software appeared to work well after
they found and fixed some minor problems, but it was decided that we
should run for the night on the old TCC because of the possibility of
undetected bugs.
The telescope was not opened at sunset due to threatening clouds and
rising humidity.  Once the humidity stabilized and the clouds began to
clear, the telescope was opened at 21:50, and AOTF began observations.
2nd half observing specialist: Karen Gloria
Second half ran very smoothly, thanks to Russet's setup work and that
of the AOTF folks.  A lot of images were obtained with the AOTF.
