Yesterday morning we did BCM calibrations, but it was found that the unser was saturated so the data was not useful. Dave Mack came in and power cycled the unser and the rates are much more reasonable now https://logbooks.jlab.org/entry/4102233. The plan is to retake them this morning around 9:30 am. Yesterday around 4pm there was a PSS mismatch that caused Hall C to drop to Restricted Access suddenly. The hall was swept and the run-safe boxes armed. The hall was back in beam permit at 5:30 pm. Due to the thunderstorms, they were not able to send stable 40uA beam until about 7:30pm. See the RC summary page for more details https://hallcweb.jlab.org/wiki/index.php/December_16,_2022. We are currently in the second cycle of setting 1 of large x at HMS 35 degrees. 

Let's discuss this further at the RC Meeting at 11am today.
