(The format in 2018 was 5 member team, 4 up on each event, three scores counting.)
It is called the "Adrian Stan Team Championships"
(This competition is one that British Gymnastics says is included in the decision on the World Championships Team ... although I don't think Phoebe is in the running, Amelie Morgan is, and should be competing here.)
Last year Phobe & Amelie Morgan competed as part of The Academy's "Senior" team although they were still Juniors ... The Academy won the team title ... with Amelie winning Gold in the Senior AA and Phoebe winning Bronze!
I expect to see scores (maybe live?) on the BG Score app (App Store ; Google Play)
There may be (??) a webstream linked on the BG Score Facebook page ... apparently there was one in 2018 that I didn't try to watch.
The competition runs in three "Rounds" on Saturday from ~2:30am PDT to ~12:30pm PDT ... and two "Rounds" on Sunday from ~2:30am PDT to ~8:15am PDT.
