TITLE: 03/03 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 148Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY:
H1 started the day Observing and then transitioned for Commissioning, but the thermalized H1 only lasted 21min of Commissioning before a lockloss.
Relocking was surprisingly not trivial with mainly the DRMI causing grief, but after a second Initial Alignment was run, DRMI managed to lock. Still seems unhealthy (even with our quieiter microseism.
