First I got the IFO to DC Readout so that IR is resonant in both arms, then opened the ALS shutters and misaligned PZT2 on each arm according to  ALOG 35979.

The reference images were taken at 04:13:00 UTC (21:13 PST) on 2017-08-28.  Then power up occurred at 04:21:50 UTC and reached nominal power at 04:24:30 UTC. 

I've shuttered the ALS at  05:42:00 UTC and reset the PZT loops to their nominal bias values.
