Much to my surprise, the B5.6 flare came from plage AR2810 (obviously pissed about being demoted).

AR2810 contains several filaments which may have produced ejecta given the long duration of the flare. AR2810 is near Zero degrees and directly Earth-facing, so we may have a small CME

The SDO website seems to be down tonight, but I found movie of the flare from GONG's Learmonth observatory:
