TITLE: 06/21 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 68Mpc
OUTGOING OPERATOR: Jeff
CURRENT ENVIRONMENT:
Wind: 18mph Gusts, 16mph 5min avg
Primary useism: 0.06 μm/s
Secondary useism: 0.09 μm/s
The arc of wind seismic noise is coming down after the EVE windstorm.
QUICK SUMMARY:
Looking much better than yesterday. Jeff handed over a nice looking H1 lock with 65Mpc range & nice looking DARM spectra. Violin modes look like they could be reduced...perhaps something I can do later in the shift since L1 is down for the night (unless they come down on their own).
Just after I hit submit, H1 dropped out of lock! (No obvious issues)
Previous lock was 1hr 13min.
