5372	01:23-03:11	01:48	PFIP cover temperatures approaching dew point.	Called: Herman Tested to make sure the sensors were working properly.
5373	09:08-09:08	00:00	Large Target sensor errors for all sensors on segment 41 (2:4). This is the 6 sensors for that segment only.

Ops Comments	none

TO Comments	Cloudy most of the evening. Moderately high humidity at beginning of the night.

RA Comments	Mostly clear at sunset. Took L/V twilight flats, but had to close for humidity during last 3 V skyflats. Priority is sci. Late start on sky due to eng work dealing with tracker temp monitoring system (HK).
