STATE of H1: Observing at 134Mpc
INCOMING OPERATOR: None
SHIFT SUMMARY:
In short H1 was tough to lock tonight mostly due to Earthquakes, a sudden spike in wind, potentially a lighning storm, and poor alignment.
ALS X had a PLL PDH error and gave me an ARM In fault code
Crystal Frequecy out of Tolerance
But it seems to have resolved the issue with out any real intervention from me.
Had many locklosses that I could not explain, and the Lockloss select tool is no longer working.
To get H1 relocked again:
Restored all (except SQZ back to the point of Right After an the First Initial Alignment tonight that lead us to the Low Noise Length Control State. GPS Time: 1395274481
Touched up x and Y are for Green arms.
Had another Lockloss @ PRMI and then Ran another Initial Alignment and I was able to get to NLN right before the end of the night.
Accepting the H1:SQZ-OPO_PZT_1_OFFSET in SDF.
Observing reached at 6:53 UTC
