OPS Wednesday eve shift summary

TITLE: 06/08 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 133Mpc
SHIFT SUMMARY:

Lock#1

We aquired NLN at 23:00UTC and went into observing at 23:03UTC, we went out of observing at 02:45 due to a lockloss.

Lock#2

Xarm went through increase flashes (~5minutes), then we went through PRMI which locked fairly quickly then DRMI locked.

The lockloss rang up a violins a bit so we had to wait in OMC_WHITENING for them to damp just like in the last lock

NLN at 04:04 UTC, in observing at 04:07UTC

Chris swung by to turn off the water pump from 23:05TUC to 23:15
