Ops Day Shift End

TITLE: 08/25 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 154Mpc
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY: Observing and have been Locked for over 14 hours now. This has been a very quiet shift. We had some commissioning earlier, and then had an earthquake coming in that was in the middle of the green earthquake zone so we decided to use the Hi ASC Gain button (first tested 86364). It turned out that the earthquake was so small that we didn't even need to go into Earthquake mode, but it was a good second test of this mode, and I found an import error in the script that was easy to fix but might  have been bad if it had been found by someone facing an actual lockloss-causing earthquake.
