Ops Day Shift Start
TITLE: 12/31 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: TJ
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 4mph Gusts, 3mph 3min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.18 μm/s
QUICK SUMMARY: H1 lost lock at 14:43 UTC, ending this lock stretch at just over 29 hours. The online lockloss tool has not been updating since 12/26 at 20:14 UTC (5 days ago), so I don't know of a cause yet, but I plan to look into it. H1 is currently automatically relocking and up to RESONANCE.
- Wind low, secondary microseism trending down to around the 50th percentile
- LAB2 DM still in error
- All other systems nominal
H1 back to observing at 16:40 UTC. Fully automatic relock with an initial alignment.
