RHIC

- still only one plane transverse (since Friday)

- yesterday during 111x111: optimization

- background increased together with coincidence rate, so no concern

STAR

- magnet chiller work still not completed

- will have to run at field-off for 1.5 days or so

- observing more blue background than yellow

- but not when sPHENIX is not in collision
