We have been running smoothly after beam was back to us yesterday around 6pm. We have accumulated charge of ~6.9C since Wien flip on Thursday. We will continue running production today and tomorrow morning. 
Moller measurement is scheduled tomorrow starting around noon. Experts are informed already.

A collective summaries from yesterday:
- opportunistic access yesterday: https://logbooks.jlab.org/entry/3723619
- Hall A beam was off for 6.5h to tune Hall B. Hall B tuning went well, no change made to the injector (https://logbooks.jlab.org/entry/3723742)
- Resumed production: https://logbooks.jlab.org/entry/3723732
- Compton background rates are 4-5kHz (DSbg2) 3.5-4.5 (DSbg1). A period of higher rates observed few times throughout the night.
