Some of the work that was completed is as follows:

A 6.6 from Tonga rolled through around 20:20UTC, it started tripping watchdogs when the R wave came through (peaked at just over 10 on NUC10)

20:49 UTC ISI BS stage 2, ITMY stage 1 & 2 watchdogs tripped

21:23 ISI HAM7 wd trip, maybe from Jim moving stuff arond the LVEA? Verbal called out a glitch beforehand (all the cps sensor saw it)

DIAG_MAIN message was flashing occasionally - TIDAL LIMITS: X_ARM_CTRL_OUTPUT within 10 percent of limit
