20:36:51- 20:37:40 Drop from OBSERVING
This was purely accidental. I had too many windows open on my Desktop, and was positioning a browser with GWIstat on it (so I could watch it during the next drop from Observing in a few minutes for the CALIBRATION measurement), BUT my fat fingers or bad eyes had my mouse accidentally click the ALS_XARM All-Guardian window's OFFLOAD_ETM_TMS_WFS state!
Since the arm is SHUTTERED, I don't think it did anything to ALSx (see attached LOG screenshot).
Immediately re-selected SHUTTERED, and returned the NODE to MANAGED & then H1 went back to OBSERVING.
