OPS Eve Shift Summary

Title: 1/3 Eve Shift 0:00-8:00 UTC (16:00-24:00 PST).  All times in UTC.

State of H1: Observing

Shift Summary:  Started the shift with an unlocked IFO due to EQ.  After EQ ringdown, aligned and locked IFO.  Since going to Observing, we have been watching the slow degradation of power via POP_A_LF, much like last EVE.  At one point we attempted to reverse the trend by adjusting ETMy pitch, but were thwarted by WFS control loops.

Incoming operator: Jim
