Thursday Morning Ops Shift Start

TITLE: 03/20 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Aligning
OUTGOING OPERATOR: Oli
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 37mph Gusts, 25mph 3min avg
    Primary useism: 0.05 μm/s
    Secondary useism: 0.44 μm/s
QUICK SUMMARY:
H1 was locked for 12.5 hours but lost lock due to High Winds at 13:39 UTC .
When I arrived H1 was still struggling to lock while the winds howled aross the the roof of the CS.
So far I have run an Initial_Alignment, and taken ISC_LOCK to IDLE, & Observatory mode to Wind.
When the tumbleweeds stop running across the road we will be ready to lock!

The hourly forcast is leaning less toward Compact Binary Collisions and more toward Tumbleweed Traffic Collisions, so watch out for those tumbleweeds.
