TITLE: 12/17 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
INCOMING OPERATOR: TJ
SHIFT SUMMARY:
Microseism is still fairly high, so staying in the USEISM state.
Maintenance Activities were complete at 20:20utc (12:20pm). Went straight into locking immediately at 20:24utc & made it to pseudo-NLN at 21:23utc (1:23pm) on the first lock! Then JeffK took H1 for ~2hrs of calibration measurements.
Wind Fence work has been going on all day first at EX & then at EY. There has been small moves with the manlift for this fence work (Heard that Robert says this noise is observable in DARM).
