(* means a trouble report has been issued or appended to)
Observing Specialist: deglman
Installed and zero-step adjusted the medium-resolution gratings.
Noticed no desiccant at all in the outer PMSS canister window. The inner
canister's window seems too opaque to get a color indication.
When powering on the Pirani gauge for the afternoon checkout, the reading
was still below scale (good?).  For verification, the Varian ion pump LED
scale on the side of SPIcam was looked at.  It was indicating zero
current.  Also, turning on the LCD, a reading of 0.01 (?volts) was shown.
So SPIcam's vacuum is probably ok.  The operating temperature being near
setpoint is likely a result of the warmer weather.
Did not open due to cloudy conditions.  Calibration spectra only were
obtained for both programs.  Did not perform lens monitoring program due
to weather.  Gave up for the night at 04:30.
