Ops Eve Shift Mid-Shift Report: 5:38UTC, no locking, and issues getting MICH DARK to lock in Initial Alignment
State of H1: 9+ hours, no locks past DRMI
Current issues:
- During initial alignment, I could not get MICH_DARK to lock.
- I called Keita, who logged in to take a look.
- Alignment is good, so it's not clear why DARK_MICH isn't locking.
- I reloaded and ran each guardian in the ISC screen through it's INIT state, hoping to find that that cleared up the issue with DARK MICH, but it didn't.
- Attached is a plot of ASAIR A RF45 Q ERR and MICH out showing ther signal running away.
- Additional assistance is being sought.
