Thurs EVE Ops Transition

TITLE: 08/21 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 150Mpc
OUTGOING OPERATOR: TJ
CURRENT ENVIRONMENT:
    SEI_ENV state: SEISMON_ALERT
    Wind: 12mph Gusts, 6mph 3min avg
    Primary useism: 0.05 μm/s
    Secondary useism: 0.17 μm/s
QUICK SUMMARY:

H1's been locked 3.25+hrs.  TJ passed on what he needed to do for relocking earlier (I've not had to lock H1 for any of my last 6-evening shifts in a row this week...we'll see how tonight goes for my last (7th EVE) shift of the week!).  Environmentally, we had a small EQ from Japan roll through, winds are low, and µseism has slowly popped above the 50th percentile in the last 24hrs.
