Monday Ops Mid Day Shift Report


TITLE: 04/01 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: None
CURRENT ENVIRONMENT:
    SEI_ENV state: SEISMON_ALERT

    Primary useism: 0.08 μm/s

QUICK SUMMARY:
Some Commissioning was being done until the 16:23 UTC Dophin Crash.
Took all SUS to SAFE
Took all SEI to ISI_DAMPED_HEPI_OFFLINE
Took HAM1 HEPI to MASTERSWITCH_OFF
CDS started restarting DAQs at 16:53 UTC ish

The FC SUS kept trying to put itself into aligned everytime we went into prep for locking even though ISC_LOCK was in IDLE.
I then Manualed ISC_LOCK to IDLE then took SQZ_MAN to Down, then Paused SQZ_MAN and finally I took FC to SAFE for good.

17:33 UTC Took all the SUS back to Aligned.
Then took ISI's & HEPI's back to ISOLATED.
Then took SEI_ENV back to Calm
Started Initial_Alignment 17:53 UTC
Increase_Flashes ran for both arms

IA could not get passed Input align due to IMC unlocking issues seen on friday's Alog 76793

Once the Issue was Identified I took all sliders except for SQZ to 1395811454 ( tail end of the last Initial Alignment) 

Y arm looked bad so I took Yarm sliders only to 1396030446 (Tail end of Increase Flashes)  to get good Y arm Values in Green arms Manual.

INITIAL_Alignment started again and completed near 19:07 UTC.

NOMINAL_LOW NOISE has been reached 19:49 UTC.
