Thurs EVE Ops Transition

TITLE: 12/27 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Wind
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
    SEI_ENV state: USEISM
    Wind: 20mph Gusts, 15mph 3min avg
    Primary useism: 0.07 μm/s
    Secondary useism: 0.78 μm/s
QUICK SUMMARY:

Drove in to some very strong winds (see attached), but they have since calmed down such that (after an alignnment), Tony has gotten H1's ISC_LOCK beyond PRMI!  (currently at ENGAGE ASC).  In addition to the very windy last-9-hrs, the secondary µseism took a turn for the worse in the last 24hrs (but if you squint you might see it drift down over the last 6hrs).  With all this said (lower winds and µseism), here's hoping H1 and the earth can conspire for a return to Observing!

[H1 currently powering up (woo woo!), AND violins are looking fine---not rung up for this first look for H1 since the last lockloss 10hrs ago.]
