Updates: - 1) S. Covrig-Dusa informed that operation limit on Carbon-foil is 85 uA

2) After discussing with Ops, we decided NOT to do the high-current test (up to 80 uA) 
since we are currently running at 60 uA @ Hall C, and soon will be taking 40 uA on other targets, 
so there is no need for us to do the high-current test.

3) Ops wil try to bring Hall A at 45 uA while keeping Hall C at 60 uA (and will inform us ahead of time)

Comment: - From MCC meeting, the actual tests high-current tests will start at 10:00 am, since ~2 hrs of preparation

Since yesterday, Ops concluded maintenance day and returned beam to Hall C during late Swing shift.
Data taking has continues without any major issues.

A nice summary of Owl shift is given by C. Morean: https://logbooks.jlab.org/entry/4112773

Today at ~8:30 am, Ops will attempt high current test to both Hall A(?) / C, for up to 80 uA.
>From MCC, meeting, Operational restrictions are set take up to 80 uA on Carbon target.
The tests are expected to take the entire day shift. 

Plan is to just follow the items on run-plan, once high current studies conclude.

We will not have an RC meeting today (unless spokespeople say otherwise)
