Ops Day Shift Summary
TITLE: 08/24 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 51Mpc
INCOMING OPERATOR: Jeff B.
SHIFT SUMMARY: Lost lock for unknown reason. Had to make a significant adjustment to PRM in YAW to lock PRMI. Made it to NLN. While running a2l PI mode 27 ran away and I lost lock again. Succeeded in making it back to NLN and did not attempt to run a2l again. Set to observing. Succeeded in damping PI mode 27 early on.
Have transitioned the INJ_TRANS guardian back to INJECT_SUCCESS.
