All,
	looked at V002 of Orbit 91 ATS; I approve.

	Contacts all line up with USN scheduled contact times, good.

	Sun-pointintg maneuver vector points us in safe directions at 
time of maneuver and at ascending and descending times for next orbit:

	Instrument commands look like the STF, per Ken's script, and 
line up with ascending and descending times for this orbit.

	Moon in Lo FOV times look good within a couple of hours, 
which is how it always is.
