TITLE: 06/27 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY:
Currently relocking and stuck not being able to get past DRMI due to it not wanting to lock and some previous ALSX crystal frequency issues. Ibrahim is working on trying to fix that.
When we went back into Observing after Commissioning today at 21:20 UTC, we had accidentally left the beam diverters open, and didn't notice for 20 minutes, so between 21:20 and 21:41 UTC the beam diverter was open. Once we noticed, we went out of Observing, closed it, and then went back ito Observing. tagging detchar

Just want to specify that the only beam diverter left open was the POP beam diverter! All other usually-closed beam diverters were closed.
