Tuesday Ops Day Shift - A Light Maintenance Day.
TITLE: 06/10 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
OUTGOING OPERATOR: Ibrahim
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 4mph Gusts, 1mph 3min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.18 μm/s
QUICK SUMMARY:
H1 was in IDLE when I arrived.
I will start trying to lock now.
I've changed the sign of the damping gain for ITMX 13 in lscparams from +0.2 to -0.2 after seeing it damp correctly in 2 lock stretches. The VIOLIN_DAMPING GRD could use a reload to see this change.
I have loaded the violin damping guardian, since the setting RyanC found still works.
