Ops Day Shift End

TITLE: 11/20 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: Currently at low noise, PEM characterization all day and one SQZ measurement started. There was one lock loss during the shift caused by us trying to move the corner station sensor correction off while in lock to allow Robert and a UW visitor look at the ITMY seismometer. Didn't work. Relocking was an initial alignment and then waiting at DRMI while we still had SC off, but all auto.
