J. Kissel for the Commissioning Vanguard

We had a good solid lock stretch under RF DARM (not yet on DC readout, but cavities fully resonance, some ASC loops were engaged) from 2018-08-15 19:19 UTC to 20:48 UTC. And from 20:00 UTC to about 20:40 UTC, the detector was left alone, undisturbed while we were in our daily commissioning meeting.

A good stretch of data to use for looking at things offline!
