Dear Collaborators,

This is your Sunday GEp-V update. We have been taking continuous production data over the last 24 hours with 89% efficiency (ABU/(ABU+BANU)). Accelerator went offline for about 45 min to 1 hr periods for a couple of times, but overall they delivered stable beam. 

Important incidents that may need attention:
- MCC found 'Hall a Downstream Ozone sensor' might need to be calibrated or changed. They have alerted ESH&Q to change it during a maintenance day. https://logbooks.jlab.org/entry/441653
- Some alarms/issues wth "ECal pump pressure left" during the OWL shift. Thanks Don Jones for taking care of it during the early hours! https://logbooks.jlab.org/entry/4416915
- DAQ live time dropping to 0% presumably due to a "Busy ECal crate 5". Thank Alex for taking care of it! https://logbooks.jlab.org/entry/4416945 From Alex's log entry suggests adding 'sbsecalROC35' to ECal reset GUI?

Experiment progress:
-Charge collected during the last ~24 hour period: 1.486 C
-Total accumulated charge at Kin3 so far: 54.11 C (Goal 100 C)
-Total accumulated charge at Kin3 since July 9 Day to July 13 Owl: 4.64 C
-Effective experiment running efficiency since July 9 Day shift (ABU tot)/(AU tot + BANU tot): 90%
