Sat EVE Ops Transition

TITLE: 10/25 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 148Mpc
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 15mph Gusts, 12mph 3min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.55 μm/s 
QUICK SUMMARY:

H1 has been locked at NLN over 2hrs (yay!) after a rough week of no observing since Mon night.  Ryan gave me a great summary of the issues/saga that went on all the way up till this morning when RyanS, Sheila, & Elenna fixed H1!

OPS ASSUMPTION:  With H1 appearing back to normal, will assume there's an OWL shift for Tony (unless I hear otherwise)

OPS Handoff from RyanS:

We did just get a warning of an EQ and this one M6 in the South Pacific, AND the EQ Response graph has this EQ squarely on the "HIGH ASC" line.  Because of this (and high microseism and the locking issues of the week), will proactively take H1 out oObserving to transition the ASC Hi Gn button a few minutes before the R-wave arrives (timer set!)
