QUICK SUMMARY:
After a lockloss while holding ISC_LOCK at LOWNOISE_ASC to fix the TRANISTION_FROM_ETMX issue, we shifted focus to fixing the PRCL1 issue we were having with DRMI, so we were holding in DRMI for a bit. Once that was fixed we went back to holding in LOWNOISE_ASC. after that Commissioning was started.

While waiting for 50+ MPH winds to blow away, I started an Initial Alignment.
This was going well enough until the SUS SRM watchdogs tripped.
H1 is currently sitting IDLE, due to this wind.
