Friday Ops Eve Shift Starting report.

TITLE: 03/08 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Aligning
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 15mph Gusts, 11mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.21 μm/s
QUICK SUMMARY:

00:14 UTC H1 Aquired a Lockloss  of unknown cause.
There was a request to load the SQZ_SHG Guardian, but there was a syntax in the code that caused the Guardian node to go into error.  Simple fix took me a few minute to find and fix.
SQZ_SHG Guardian node is running smoothly now.

Corey then took H1 into Initial_Alignment, while I edited the  sqzparams.py.
Line 18  was take from 75 to 80:
opo_grTrans_setpoint_uW = 80  #reload OPO guardian for this to take effect
I then took SQZ_OPO_LR  Guardian to LOCKED CLF_DUAL_NO_ISS,  Then reloaded the Guardian code.
Once reloaded I took SQZ_OPO_LR back to LOCKED_CLF_DUAL. 

Then tried to adjust the OPO_TEC_TEMP, this was a mistake. I could tell that something wasnt correct because I couldn't get the SQZ-CLF_RFEL_RF6_ABS_OUTPUT back to the same hieght it was before while adjusting the OPO_TEC_TEMP. Contacted Sheila.
She informed me that the SQZ_CLF_LR should be locked when doing this.

Once locked the SQZ-CLF_RFEL_RF6_ABS_OUTPUT went up and Looked much better.

Relocking notes.
Initial_Alignment is finished and I'm trying to relock and I have not had success past DRMI. But the night is stil young.

Update:
NOMINAL_LOW_NOISE reached at 2:50 UTC
Observing reached at 3:02 UTC
