OPS Tuesday day shift summary
TITLE: 02/04 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Preventive Maintenance / Lock Aquisition
INCOMING OPERATOR: Corey
SHIFT SUMMARY: Busy maintenance day, PR2 spot move took a little while but we had trouble getting started. The violins look elevated as we're getting to ENGAGE_ASC, I envision us spending time in DAMP_VIOLINS or OMC_WHITENING to damp them down during this aquisition.
