Dear all,

A final summary of the RC meeting from me since I have handed over to
Silvia this afternoon!

* MCC plan spin dance for day shift tomorrow: expected to take ~8h. Stepan
suggested priority of special runs as:
1. Zero field
2. Low luminosity (7nA)
3. Empty target

* Krister would ideally need morning access to close up the Moller magnet
(~1h), Florian and Efrain would need a quick access to check the BAND laser
system.

* Valery would like to do a ~1h test with a trigger which excludes low Q^2
events.

* Hall C plan a ramp test for Friday, which would coincide with RF recovery
-- more opportunity to access the hall if needed.

* Change to pass-2 is planned for Tuesday start of day shift.

* Priority hall order for the coming week is A, then B.

* Nathan has made the run-start /end dialogue box unmissable and utterly
unavoidable -- which will hopefully lead to more reliable comments in the
RCDB! https://logbooks.jlab.org/entry/3751247

* Our accumulated charge up to now for this autumn's run is 9mC -- and we
have taken ~ 2.8 x 10^9 triggers in production runs.

Beam had returned this morning and by the powers of Mike Tiefenback it was
being tuned for production.

Many thanks and a happy rest of run!

Daria
