OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
    SEI_ENV state: USEISM

    Primary useism: 0.04 μm/s
    Secondary useism: 0.45 μm/s
QUICK SUMMARY:

Happy Spring Forward Morning (& 1-hr less sleep)!

H1 just went down (after a 3h51m lock, and a 1435utc lockloss w/ an ETMx Glitch tag).  Taking H1 immediately into Initial Alignment to skip Locking ALS locklosses. 

The one Owl 932utc lockloss (also an ETMx Glitch tag) was fully automatic (after about 22min of 7 Locking ALS attempts) & no Alignment was needed.

Looks like secondary microseism hit the 95th percentile about 10hrs ago and has stayed there.  Winds are under 10mph.
