OPS Eve Shift Summary

TITLE: 08/09 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY:

IFO is LOCKING at PREP_FOR_LOCKING

IFO was locked for the majority of the shift with one lockloss 04:07 UTC killing a near 9hr lock. Cause still unknown but seems like a glitch from looking at the saturation plots on the H1 lockloss tool.

H1 had poor flashes in DRMI and even worse flashes in PRMI so after letting it try for a bit, I started an initial alignment, which just completed fully auto. We're now locking hopefully also fully automatically with H1 in managed (for the OWL shift).

LOG:

None
