MAJOR SOLAR FLARE A major solar flare measuring X1.0 was observed around sunspot 1893 at 10:26 UTC Tuesday morning. A type II radio emission with a velocity of 1049 km/s was associated with this event. The active region is about to rotate onto the southwest limb and is no longer in the best position for Earth directed eruptions. Further updates regarding a possible CME to follow.
CME Update: A coronal mass ejection (CME) is now visible in the latest imagery released by STEREO Ahead COR2. More updates regarding a possible Earth directed component once Earth facing LASCO imagery is available.Click HERE for a video of the solar flare and CME.SUMMARY: 10cm Radio Burst
Begin Time: 2013 Nov 19 1020 UTC
Maximum Time: 2013 Nov 19 1021 UTC
End Time: 2013 Nov 19 1027 UTC
Duration: 7 minutes
Peak Flux: 530 sfu
Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications. ALERT: Type II Radio Emission
Begin Time: 2013 Nov 19 1024 UTC
Estimated Velocity: 1049 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.Updated 11/18/2013 @ 13:50 UTC
