First-Half Observing Specialists: Deglman & Hastings
	The high-resolution gratings were installed in DIS and then zero-step
adjusted.  Xiaohui Fan obtained calibration spectra on the DIS for PU01.
During the afternoon checkout, saturated desiccant (pink) was discovered
in one of the PMSS canisters.*  The dome was not opened due to weather.
Second-Half Observing Specialist: Hastings
	Not much to report. Stayed cloudy and we stayed closed all night.
