OPS Thursday DAY shift summary
TITLE: 12/13 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 155Mpc
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: We stayed locked the whole shift, 19hours. PRM camera is blue, 2ndary microseism seems to have flatlined, its likely from storms both off the coast and near Greenland as the arms see similar phase differences from the CS. Low frequency noise seems intermittently elevated based on DARM and SQZ dtts.
