Ops Comments	none

TO Comments	clear HPF work most of the night; clouds at end of night. AOA actuator worked and initialized once; did not push it but felt that if I did move it too many times it would fail like previous nights.

RA Comments	Moderately clear at sunset. Night devoted to HPF eng and other pri0 sci. Took LRS2 sky flats for possible sci target later in night.
