OPS Thursday eve shift summary

TITLE: 11/17 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 157Mpc
INCOMING OPERATOR: Austin
SHIFT SUMMARY: We've been locked for almost 7 hours.

For the relock we couldn't get DRMI or PRMI so we went through CHECK_MICH, then PRMI twice but after the 2nd PRMI DRMI was able to lock easily. ISCT6 AS AIR camera flashed blue at 00:24 UTC while we were in CHECK_SHUTTERS (tagging CDS). Once we went through CLOSE_BEAM_DIVERTERS the SQZ_FC node went into error, which Naoki then checked out and fixed.

01:09UTC In observing

02:39UTC EQ mode activated 5.7 from Myanmar, back to calm at 02:49UTC

03:03UTC GRB-Short E453298

First snow of the season? Small flurry on site around 04:00UTC and 07:00UTC onwards.
