Ops Day Shift Summary

TITLE: 09/15 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 112Mpc
INCOMING OPERATOR: TJ
SHIFT SUMMARY:  Took an extra long time to get relocked for reasons that aren't clear.
LOG:

17:23 Lockloss, cause unclear

Initial alignment completes without operator intervention.

Consistently losing lock at ENGAGE_ASC_FOR_FULL_IFO similar to what was noted in aLog 51942.  It seems that near the end of this state, INP1 Y and SRC2 Y are pulled away from 0 (these were most noticeable at least).  Called Keita and he is looking into it and will return my call shortly.  Winds are 20-30 mph during this relocking, so probably not helping.

Tried waiting at PREP_ASC for a few minutes a couple of times with no luck.  About the 6th lock attempt, it finally made it past ENGAGE_ASC, but lost it at INCREASE_POWER as the buildups started to decrease. 

Getting alot of SUS saturation verbal warnings (IY, IX, EY, EX, OMC) in ENGAGE_SOFT_LOOPS.

21:45 Observing, just needed Keita's moral support
