Ops Day Shift Start
TITLE: 03/12 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 141Mpc
OUTGOING OPERATOR: Ryan C
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 15mph Gusts, 11mph 3min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.31 μm/s
QUICK SUMMARY: Locked for just over and hour, looks like Ryan had to accept some SDFs overnight, and there were some ALS issues yesterday, but we had 3 relocks overnight. No alarms this morning.
Since our range is a bit lower right now I ran the coherence check template. CHARD is definitely showing come coherence so we could probably run A2L, though with our other issues going on perhaps there is something else afoot.
