AR 4455 Triggers R1 Radio Blackout With M3.3 Flare as More M-Class Activity Looms

Summary
An M3.3 flare from AR 4455 peaked at 1650 UTC on June 2, driving R1 radio blackout conditions alongside other isolated M-class flares.
Regions 4455 near center disk and 4461 on the southeast limb produced the activity that disrupted radio communications at the minor R1 level.
A large eruption just beyond the eastern limb occurred at the same time, leaving forecasters uncertain whether the event launched an Earth-directed coronal mass ejection.
Coronagraph imagery in the coming hours will be used to determine any CME trajectory, while a high chance of additional M-class flares is expected through June 4.
