TITLE: 04/07 Eve Shift 23:00 – 07:00 (16:00 -00:00), all times posted in UTC

STATE of H1: Observing

INCOMING OPERATOR: Jim

SHIFT SUMMARY: Started in Observing at around 108 Mpc, dropped out briefly to troubleshoot SQZ_MANAGER issues with Sheila. At around 20:00 UTC the range dropped by about 10 Mpc and stayed low for ~2 hours. Aside from a slight wind increase and a string of small earthquakes, I’m not sure what caused it. Range has since come back up to 106 Mpc.
