Ops Comments	none

TO Comments	check seg 9:7 for collisions before running SAMS/SCS. internal dust count 26k higher than external on the 1um scale.

RA Comments	Cloudy at sunset (00:04 UT). Priority is sci and high-pri eng. Work downwind warning (wind out of north) at start of night prevents taking of L/V twiflats.
