QUICK SUMMARY:

Relocking notes:
Mysterious lockloss at Prep_TR_CARM after a suspicious HAM6 saturation.
Some investigations show me a possible CPS glitch on HAM 6 now. tagging SEI. See screenshot.


ALSX went through Increase flashes then had a fault for PLL & PDH, going to green arms manual.
I unlocked ALSX and requested Lock_slow_no_WFS. this did not fix the issue, but it did eventually start staying locked for longer.
so I sent it to Locking ALS to see if I'd get another lockloss. So far its going well.
made it to NLN at 17:21 UTC.

17:24 UTC Observing reached.
