Key updates for the past 24h (Fri Day+Swing and Sat Owl):

Last 24h have been smooth data taking with few subsystems issues from GEM HV(https://logbooks.jlab.org/entry/4411586) and ECal Cooling (https://logbooks.jlab.org/entry/4412001). Thanks for the subsytem expertrs for resolving the issues quickly. All the Crew workers were really efficient handling the production and addressing the issue on time. 

We could recieve 18.5h of beam during this 24h. 15.95 h of beam were used for production, however we could lost 2.43 h of beam in changing run, issues from GEM and fixing CODA which accounts for 86% of up time.

We are following the same run plane as on Thursday.

- Total Accumulated Charge at Kin3 so far: 44.61 C (Goal: 100 C)
- Total Accumulated Charge at Kin3 since Jul 04 Swing: 1.94 C

- Spot change postponed to Wed/9; evaluate polarization measurement before that

Current issues:
- Installation of Copper plate
- Monitor scalers and replay for missing/bad data that may require DAQ components reset/reboot/run restart
