Dear Collaborators,

We have been continuing to take production data at 20 uA on LH2. We had some above average (for the last few days) DAQ issues during the last 24 hours that caused some downtime. Our running efficiency was ~81%.

Important incidents that may need attention:
- During the day shift, shift-crew had to power-cycle the ECal cooling system https://logbooks.jlab.org/entry/4417139
- Few ECal HV cards seems to be going bad and they will need either an opportunistic access or an access during the maintenance day on Thursday.
- We are experiencing some increased CODA instability (live time dropping to 0 during the mid run and etc.) which maybe we can discuss.

Experiment progress:
-Charge collected during the last ~24 hour period: 1.443 C
-Total accumulated charge at Kin3 so far: 55.77 C (Goal 100 C)
-Total accumulated charge at Kin3 since July 9 Day to July 43 Owl: 6.09 C
-Effective experiment running efficiency since July 9 Day shift (ABU tot)/(AU tot + BANU tot): 88%
