Ops Eve Shift Summary

TITLE: 11/27 Eve Shift 2030-0200 UTC (1230-1800 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: The last of the PEM measurements were done this evening when H1 was locked, but a couple of locklosses (both of which seemed to be caused by activity in sensitive areas in the LVEA) limited the amount of time at low noise. Following the most recent lockloss, I'm leaving H1 in 'IDLE' for the long weekend before the upgrade phase begins on Monday.
