Notes from the 9 o'clock meeting (5/17)

- yesterday’s STAR access finished early

- successful overnight shift for RHIC: machine is done except for re-bucketing

- collisions overnight for STAR

- first collisions at sPHENIX seen by ZDC scalers (7 bunches 500 Hz, 56 bunches couple kHz, no steering, no collimation)

- today’s access might finish early around 4:00pm

- overnight: collisions for STAR, Angelika finishes collimation for sPHENIX

- that means collisions for sPHENIX overnight that maybe useful for timing in the MBD

- tomorrow morning 8:00am store for re-bucketing

- after that (probably starting sometime during tomorrow’s evening shift): sPHENIX commissioning begins
