Issue Time: 2026-05-02 11:11 UTC
ALERT: Type II Radio Emission
Begin Time: 2026-05-02 10:51 UTC
Estimated Velocity: 641 km/s
Comment: Likely associated with C-class flare acitivity originating from AR 4420 on the west limb.
Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.
