Hall C pass change took place yesterday morning, and it was completed relatively quicker than anticipated. Since then, beam delivery and data quality have been good, except for an incident this morning around 7 AM when the SBS magnet correctors tripped. Other than that, there were no major issues, apart from frequent DAQ crashes (RC GUI freeze), GEM chamber trips, and HV spikes. Refer to the shift summaries for further details.

Major Activity:
* Around 7 AM, the SBS magnet correctors tripped (https://logbooks.jlab.org/entry/4442963). After several back-and-forth phone calls with the Crew Chief and Hall Techs (coordinator), I was able to get on a call with the SBS magnet expert (Ellen Becker). She arrived at 9:30 AM, with RadCon arriving just before that. Ellen is unsure about the cause of the issue or how long it might take to resolve. Therefore, we decided to survey the hall and remain in controlled access until the issue is resolved.

Plan for today:
Once the SBS magnet issue is resolved, we will resume production data-taking.

Since yesterday's Day to today's owl:
* Total Accumulated Charge at Kin3 so far: 83.13 C (Goal: 100 C)
* Total Accumulated Charge at Kin3 since yesterday's update: 0.76 C
