TITLE: 07/17 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 113Mpc
OUTGOING OPERATOR: Cheryl
CURRENT ENVIRONMENT:
    Wind: 13mph Gusts, 9mph 5min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.08 μm/s

Just had 5.3 off coast of Oregon!
QUICK SUMMARY:

H1 had been locked 6+hrs, but as I was typing Cheryl and I saw multiple signals (ASC, tidal, seismic blrms) all grow.  Later saw that this was a 5.3 Earthquake off the SW  Oregon coast!  There was no Verbal warning, and I think I missed it on SEISMON because this was happening as I was logging into the computer (maybe we can have SEISMON or a smaller modified indicator/alert window up on the wall).

At any rate, after the lockloss 15:03utc, I took ISI_CONFIG to LARGE_EQ_NOBRSXY.

Just a note for later:  There are plans for the Wednesday Calibration measurements (roughly 1-3pm local).
