Ops Eve Shift End

TITLE: 07/16 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: TJ
SHIFT SUMMARY:

Currently relocking and in MOVE_SPOTS. This last relock was looking so bad up until ENGAGE_ASC_FOR_FULL_IFO, I am very surprised it made it (40min build ups). The first lock reacquisitoin of my shift, ALSX was having some issue with the crystal frequency and was losing lock a lot. Also, there were many times when it was looking really bad but would hold on (ndscope). Besides ALSX having trouble that first round of relocking, there haven't been any issues.
