EVENT LOG: M6.5 SOLAR FLARE     SOURCE: Sunspot 2027

A rather noisy and long duration solar flare event measuring M6.5 was observed around sunspot 2027 at 14:05 UTC. An asymmetrical halo CME became visible in both STEREO Ahead and LASCO C2 imagery following the event. Analysis suggests the plasma cloud is directed mostly to the east and away from our planet. Only a minor glancing blow at best will be possible.

CME prediction model released by the Goddard Space Flight Center shows a glancing blow impact possible by April 4th. Based on CME imagery, I do not expect a large increase in geomagnetic activity. More to follow.

Updated video of the CME from earlier today suggests only a very small portion of it may be directed towards Earth. A majority of the ejected material is directed to the east and away from our planet. It would appear that a glancing blow at best is to be expected. Click on the image below to watch the video.

Video presentation of the flare event and CME is now available.

Coronal Mass Ejection (CME) now visible in the latest LASCO C2 imagery. Appears to be directed mostly to the east.

Coronal Mass Ejection (CME) now visible in the latest STEREO Ahead COR2 imagery. Imagery located to the right.

Type II Radio Emission with an estimated velocity of 903 km/s detected. This indicates the potential for a coronal mass ejection.

ALERT: Type II Radio Emission
Begin Time: 2014 Apr 02 1323 UTC
Estimated Velocity: 903 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.

10cm Radio Burst (TenFlare) lasting 26 minutes and measuring 3700 sfu detected.

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Apr 02 1341 UTC
Maximum Time: 2014 Apr 02 1357 UTC
End Time: 2014 Apr 02 1407 UTC
Duration: 26 minutes
Peak Flux: 3700 sfu
Latest Penticton Noon Flux: 153 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.
