Wed DAY Ops Transition

TITLE: 09/03 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 149Mpc
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 3mph Gusts, 1mph 3min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.11 μm/s
QUICK SUMMARY:

H1 had issues last night with the SQZ (as noted by Tony in his OWL alogs), but h1 has been locked/thermalized for just over 17hrs37min.  Bring up thermalization, because the plan is for a calibration suite  of measurements to be run at 8am.  Also looks like there will be commissioning right after this measurement TODAY (830-1130amPDT).

On nuc23, the DARM .5-2kHz bands have been recovering from the SQZ issue starting 2hrs ago and look like they are at normal levels for the last hr or so (see attached).
