Begin Time: 2013 Feb 06 0013 UTC
Estimated Velocity: 548 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.
ALERT: Type IV Radio Emission
Begin Time: 2013 Feb 06 0017 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.
