OPS Thursday day shift start
TITLE: 11/23 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 151Mpc
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
SEI_ENV state: SEISMON_ALERT
Wind: 7mph Gusts, 5mph 5min avg
Primary useism: 0.04 μm/s
Secondary useism: 0.26 μm/s
QUICK SUMMARY:
- WE've been locked for 4:40, in observing since 11:19UTC
- Microseism is still nicely trending down, winds picking up a bit, EQ incoming from Bolivia
- Our range has been a little lower this current lock, SQZ looks good, maybe its from the wind/SEI configuration? Since were still in a microseism SEI config
- If we drop out of Observing I'll change the SEI config back to WINDY as the forecast has the wind continueing today into tomorrow
- ITMY5/6 continutes to be the largest violins, just under 10^-16
ITMY5 was still rising under nomial gain, so I set it to zero then switched the sign (+0.01 currently) and it seems to be dropping it, but it may be making mode6 rise ever so slightly, its hard to tell.
