Ops Eve Shift Start

TITLE: 10/17 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Microseism
OUTGOING OPERATOR: Ibrahim
CURRENT ENVIRONMENT:
    SEI_ENV state: USEISM
    Wind: 40mph Gusts, 24mph 3min avg
    Primary useism: 0.20 μm/s
    Secondary useism: 0.39 μm/s 
QUICK SUMMARY: H1 is currently down after a tough day of locking. Sounds like environmental conditions (mainly microsesm and wind) are causing difficulties with getting H1 back up, and I'll be on the lookout for the strange 1Hz ringup from earlier today.
