Some of the work that was completed is as follows:
- Laser Safe transition
- ALS investigation cont. at both ends
- EE/CDS UPS checks
- TTFSS investigation
- ISC_EY front end replaced alog80395
- Reheat coil checks alog80401
- HAM1 ION pump investigation/swap
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
