OPS Day Shift Summary

TITLE: 03/30 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY:

IFO is in IDLE for PLANNED MAINTENANCE

HAM 1 team has been working on JAC from the bifurcated HAM1 area and the control room throughout the day. SPI and BHSS work continued in the optics lab.

IX has been a bit finicky and tripped the SW WDs. They didn't seem like they were untripping and we were seeing the counts get worse with the damping loops. Additionally, the rocker switch death flashed a few times. Jim fixed this by turning off SUS damping, then letting the ISI damp until counts visibly went down before turning on damping everywhere.

BSC2 platform work and HAM3 cabling continued.
