(* means a trouble report has been issued or appended to)
Final work was done today for the PMS pump and pump controller
installation.  All systems were tested and functioning as prescribed.
Gordon Richards observed with Dis for the Adler program, no problems
encountered.
The lens program obtained data sets on two lens, no problems.
Alan Dierks and Austin Tommany then used SPICAM.  Observations were
delayed by a problem with the fill.  The dewar had been topped off prior
to installing the instrument on the telescope, but it ran out of nitrogen
soon afterwords(false fill, autofill).  A quick fill was done and we were
back on.
Tommany observed for the first hour, under poor seeing conditions.  Alan
then came on to observe.  We did encounter a failure with the guider that
required a reboot of the guider system.  I will email Jeff Morgan
detailing the event.  Alan lost one, 10min exposure.
Tommany continued afterwords using SPICAM.  No problems were encountered,
other than poor seeing.
Alan commented that his run went well, other than the lost exposure to the
guider.
Austin Tommany noted this was the first data he had obtained in 8trys.
Even poor seeing and murky skies were fine.
