Issue Time: 2025-10-21 21:09 UTC
ALERT: Type IV Radio Emission
Begin Time: 2025-10-21 20:11 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

Issue Time: 2025-10-21 21:08 UTC
ALERT: Type II Radio Emission
Begin Time: 2025-10-21 20:07 UTC
Estimated Velocity: 2474 km/s
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.
