Around the time of the first power glitch this morning both models on h1susauxh2 recorded a single DAQ CRC error by both DC0 and DC1.
Attached plots show the 3 mains phases for this glitch, and the second plot shows one phase and one of the CRC errors (they all happened concurrently).
This glitch was more severe than usual, with two phases being significantly reduced in voltage for several cycles.
I will clear the CRCs next time H1 is out-of-observe.
