- 0045-0047 Accidental Calibration button push dropped us out of Observing (Louis), but all is well and nuc30's DARM returned within 5min.

- 0741 Lockloss, Lock#1:
- Both green arms looked pretty misaligned, so they both went through INCREASE FLASHES. Y-arm offloaded in just over 10min (after 2-rounds of INCREASE FLASHES). X-arm was stuck in its 1st round of INCREASE FLASHES for over 15min, but is now going through it's 2nd round.
