STATE of H1: Observing at 150Mpc
OUTGOING OPERATOR: Ryan C
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 4mph Gusts, 2mph 3min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.11 μm/s
QUICK SUMMARY:

H1's been locked for almost 12.5hrs  and it looks like we had a brief outage from Observing due to the SQZ dropping us out just before 1300utc/6amPDT, but SQZ MANAGER and H1 got back to OBSERVING automatically within a 5min (coincidentally, this improved the H1 Range [which had been drifting down below 150Mpc] getting it back to above 150Mpc.

Environmentally, we are doing well; useism had been above the 50th percentile and has been drifting down from this for the last 10hrs.  Winds are low and it is a cloudy and cool morning.
