TITLE: 11/07 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Microseism
OUTGOING OPERATOR: TJ
CURRENT ENVIRONMENT:
SEI_ENV state: USEISM
Wind: 8mph Gusts, 5mph 3min avg
Primary useism: 0.04 μm/s
Secondary useism: 0.77 μm/s
QUICK SUMMARY:
H1 had a bit of a day. What's new today from TJ---is that H1 is having trouble locking DRMI.
Microseism definitely continues to be the main culprit environmentally with (0.1-0.3 and 0.3-1.0Hz bands both being high and even increasing over the last 6-8hrs). Winds are now low and it is raining out.
Plan for the EVE shift is to continue with locking.
Plan for OWL shift (if locking woes continue), is to NOT set OWL shift alerts for the night, take ISC_LOCK to IDLE, and then I just touched base with RyanC about having him assess H1 locking about 4hrs after the EVE shift (~around 2AM). If locking looks better, continue locking, but if it continues to look dire, take ISC_LOCK to IDLE for the OWL shift .
