Observing Specialist, 1st Half: Frank Deglman
Observing Specialist, 2nd Half: Camron Hastings
     Rain kept us company all night, more or less. I worked on a set of
recent PMSS data. Plots of results have been left in Jon Davis' and Mark
Klaene's mail boxes. The load cell voltage jump during yesterday morning
appears to have been completely fixed by the re-tuning that took place.
The only thing worth mentioning was the anomalous voltage that A sensor
is centered on, very different from all other load cells.
	I helped Jeff Morgan pull some cable after he made some modifications
to some tertiary hardware. We stayed closed all night.
	Frank said that he took images with the instruments and that they look
fine after being cooled down.
