QUICK SUMMARY:
Lockloss from CHECK_MISH_FRINGES https://ldas-jobs.ligo-wa.caltech.edu/~lockloss/index.cgi?event=1369267224
Lockloss from TRANSITION_FROM_ETMX https://ldas-jobs.ligo-wa.caltech.edu/~lockloss/index.cgi?event=1369271157
2:15 made it back to Nominal_LOW_NOISE even though the wind is gusting up to 40 MPH out at EX.
2:27 UTC made it back to observing!!
Violins:
ITMX Mode12 was increasing, so I turned the damping off.
I tried turning the gain back on to nominal +2 after a while and it still shot right up as soon as gain was applied.
Now trying gain of -1 on ITMX mode 12. Seems to work well.
Lockloss right as Austin sat down to take Over the IFO 7:00UTC https://ldas-jobs.ligo-wa.caltech.edu/~lockloss/index.cgi?event=1369292468
