Sunspot 1667 generated strong C8.7 solar flare and possible Earth-directed CME

A solar flare registered as C8.7 was detected at 00:21 UTC on February 6, 2013. The source of the flare was decaying Active Region 1667. According to images from NASA’s STEREO-B spacecraft, the associated CME appears to be heading in the Earth direction, with expected time of arrival on February 8/9, 2013.

ALERT: Type II Radio Emission
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.
