TITLE: 12/15 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 157Mpc
OUTGOING OPERATOR: Oli
CURRENT ENVIRONMENT:
SEI_ENV state: SEISMON_ALERT
Wind: 11mph Gusts, 7mph 3min avg
Primary useism: 0.04 μm/s
Secondary useism: 0.30 μm/s
QUICK SUMMARY:
µseism is clearly below the 95th percentile in the last 4hrs! (look at secondary useism above well below 1μm/s! Woo Woo! (and winds of yesterday have actually calmed in the last hour).
H1 has been locked almost 6.5hrs---> Where in the middle of the night a M5.2 earthquake caused a lockloss at 724utc (or 1124pmPT)....Seismon/Verbal said it was Canada, but it was a NorCal/Petrolia aftershock--there was nothing from Canada on all the earthquake sites. This lockloss did require an automated Initial Alignment, but after that locking was smooth with no locklosses (thanks to lower microseism!).
