Ops Eve Shift Start

TITLE: 02/17 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 140 Mpc
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
    SEI_ENV state: USEISM
    Wind: 9mph Gusts, 5mph 3min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.53 μm/s
QUICK SUMMARY:

Currently Observing and have been Locked for 3 hours. Our range was bad, which we figured was due to squeezing being way worse than last lock and not getting better with thermalization. We popped out of Observing to adjust squeezing but it was giving us issues and we had trouble getting IR to lock (see Ryan's alog). Finally were able to get the filter cavity locked by adjusting the OPO temp, but our squeezing was still bad, so Ryan adjusted the OPO temperature again and got a tiny bit of squeezing out (-1db), but not much. Range is basically back to where it was before all this.
