(* means a trouble report has been issued or appended to)
1st half observing specialist: K. Gloria
The telescope was opened at 18:30 MDT.  It was closed briefly during
twilight for spectral cals.
Wei Zheng and Zlatan Tsvetanov observed remotely with DIS.  Their run
went mostly OK, with a couple small problems.  The T_TRACK process
died during their run, but it happened in between exposures and I restarted
it right away, so there was no loss of time.
They did loose some time when their remote Mac crashed and had to be
rebooted.
2nd half observing specialist: K. Gloria
Dara Norman and Gene Magnier observed remotely with SPIcam.  They were
getting the low level (60 Hz?) noise we sometimes see in SPIcam
images.
They lost 0.1 h at the beginning of their time due to my having to
swap out an empty LN2 dewar for DIS.  Other than that and a few cirrus
clouds, their run went smoothly.
