 Shift Summary & Observations:

- Commissioners/Ops working on relocking IFO until about 02:00.
- Set to commissioning mode – Commissioners working while LLO is down
- Set to Observation mode 06:43 – Wind low, range @ 67Mpc
- First half of the shift was spent recovering from maintenance and some commissioning work. After locking, commissioners continued to work on IFO. We have been locked since 02:00. Some glitches mostly due to commissioning/calibration work. 
- After clearing SDF, switched to Observing mode at 06:43 (23:43). 
   NOTE: The LVEA was not swept before going into Observing mode. The decision was not to risk knocking the IOF out of lock by walking around in the LVEA. The lights are on. Do not know what other noise sources are present at this time.
