August 21:
1:15 pm PDT:  D9 front fast threshold to 0x60 (was 0x90).
2:50 pm PDT:  D9 front and rear events disabled.
4:30 pm PDT:  HV drop of ~400V, performed in two steps, to 1838V.  No change to resets (30k).  RTS load to keep D9 events from being re-enabled after eclipse.  D9 fast and slow thresholds to max.
6:00 pm PDT:  HV drop to ~900V and then again to ~800V.  Rear resets before and after are 30k then 25.7k then 23.5k.  D9 front fast threshold returned to 0x90.
