Wed EVE Ops Transition

TITLE: 09/17 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 148Mpc
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 5mph Gusts, 2mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.18 μm/s
QUICK SUMMARY:

H1's been locked since last night!  (20.5hrs now)  H1 was in need of an ISC_LOCK node LOAD, but the H1 SQZ briefly dropped us out of Observing, so Tony was able to take this LOAD off the To Do List.

Seismically, there were a couple of EQs  which required EQ Mode, but H1 rode right through them (last night and during Tony's shift....no "ASC Hi Gn" transition was needed.

From last night, it looks like TJ & Jim took care of BRSy and also the violins were fixed by Ryan C (and thanks about the note on its finicky gain!)  :)
