OFI Returned to aligned... No output. Apparently this is normal.

SRM already aligned by Elenna.
Attempting to start relocking 19:00 UTC
Potential Lockloss from FIND_IR when I requested SEI_ENV to cycle between Maintenance & CALM.

Lots of saturations when we ran through LOWNOISE_COIL_DRIVERS

Unknown Lockloss from Low_Noise ASC ( We manualed over a handful of States and Ended up manualing back to this state.)

Adjusted the ALS polarization of both X and Y arms.
Ran a Manual_Initial_Alignment Finished @ 22:26 UTC

No internet do to a GC switch restart 22:40 UTC. Internet back up a few moments later.


Lots of saturations when we ran through LOWNOISE_COIL_DRIVERS again, we did not lose lock either time.

Lockloss due to DHARD P ring up while in LOW_NOISE_LENGTH_CONTROL.
