OPS Eve Shift Summary

TITLE: 08/21 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY:

IFO is in IDLE at 2W

Ryan C informed me of the Beckhoff issue that will require an early morning computer restart (alog 91611). In the meantime, comissioners Elenna, Keita and Louis were working on alignment, specifically trying to solve a clipping issue related to PR2 in PRMI acquisition. 

During this, Elenna and Louis were putting IFO in single bounce IR with green arms on X to guage the alignment at the PRC. Then, they were going to pico. They'll continue tomorrow. Details in alog 91632
