OPS Eve Shift Summary

TITLE: 11/15 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Wind
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

IFO is in ENGAGE_ASC_FOR_FULL_IFO and ENVIRONMENT

Still not locked due to wind and microseism.

Microseism just went below the 90% line where it's now lockable. As that happened we got gusts of wind from 35 to 45mph. The wind just went below 30mph so I think this lock acquisition might just work!

We lost lock over 30 times in this acquisition, making it to TRANSITION_FROM_ETMX twice before losing lock seemingly due to instability.

LOG:

None
