TITLE: 06/19 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

Currently relocking and at MOVE_SPOTS. We lost lock earlier after having been locked for 4.5 hours, with half of that locked time being spent messing with the SQZ filter cavity and trying to keep it from unlocking(85169). We still haven't figured out why it was unlocking. For the night we are keeping the FC beam spot control off. SDFs have been accepted to keep the FC beam spot control filter inputs off(sdf). We don't really think that was the issue, but we got out longest span (15 mins before LL) of a locked sqzer after turning it back off after the unlocking issue had started. We'll look more into the sqzing issues tomorrow, so for Tony: if we have SQZ issues overnight, just go to Observing without SQZing and it'll get dealt with tomorrow.
