OPS Eve Shift Start

TITLE: 11/17 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 145Mpc
OUTGOING OPERATOR: Ryan C
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 13mph Gusts, 9mph 3min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.30 μm/s 
QUICK SUMMARY:

IFO is in NLN and OBSERVING as of 17:51 UTC (6 hr lock)

Ryan C reports the same LOWNOISE_ESD_ETMX issue as before occured this morning but after moving the drivealign gains past the bias ramping and loading guardian, it seems the issue has been fixed. It technically hasn't been tested yet so we'll see when we relock.

Otherwise, wind and microseism look good. Hoping for a smooth and quiet shift.
