TITLE: 12/15 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC

STATE of H1: Commissioning/Observing

INCOMING OPERATOR: Cheryl

SHIFT SUMMARY:

Did initial alignment during the first hour. Lost lock twice before hitting nominal low noise at around 19:00 UTC. After about two hours of trying to get the observation bit to work, we managed to get into Observation mode (see Keita’s alog 45969 for more information). Maintained observation mode until 23:00 UTC, when we started commissioning. Lost lock around 23:40 UTC.

Additional notes: Hanford’s observing mode status was not showing up in summary pages or the LIGO Data Grid Status page. Keita is looking into it.
