Growing region 1967 produced strong M6.6 solar flare, glancing blow from CME possible

At 16:11 UTC today Region 1967 (S14E48, Fkc/beta-gamma-delta) unleashed its 13th and strongest M-class solar flare since it returned from the farside of the Sun. The region is rotating toward the center of the disk and is showing a trend of slight growth. Earth directed Coronal Mass Ejections (CME) from this region are possible in the days ahead.

After M2.1 at 06:44 and M1.1 at 08:41 UTC today, a strong solar flare measuring M6.6 erupted. A Type II Radio Emission, indicating a CME, was associated with a flare event. Its estimated velocity was 2161 km/s.

A 10cm Radio Burst (TenFlare) lasting 29 minutes was also reported. 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.

Update (SWPC, January 31, 2014 – 00:30 UTC):

"An asymmetric halo CME was observed in SOHO/LASCO C2 coronagraph imagery emerging from the southeast limb at 16:24 UTC.

Analysis suggests the CME was moving at approximately 1400-1500 km/s and may have an earthward component. WSA-Enlil model run is underway to determine the geoeffectiveness.

CME associated with the M2.1 flare was first observed in Lasco C2 imagery at 08:24 UTC. Analysis suggests this CME was moving around 500 km/s with very little of the ejecta being Earth-directed. It has been included in the model run mentioned above to determine the extent of any interaction."

Update (SWPC, January 31, 2014 – 12:30 UTC):

"WSA-ENLIL model analysis [for M6.6 solar flare] indicates a glancing blow from the CME is likely mid to late on February 02."

Space Weather Message Code: SUM10R
Serial Number: 607
Issue Time: 2014 Jan 30 1642 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Jan 30 1553 UTC
Maximum Time: 2014 Jan 30 1605 UTC
End Time: 2014 Jan 30 1622 UTC
Duration: 29 minutes
Peak Flux: 220 sfu

Latest Penticton Noon Flux: 156 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.

Region 1967 (S14E48, Fkc/beta-gamma-delta) continues its trend of slight growth. Region 1968 (N09E48,Eao/beta-gamma) exhibited mixed polarities in the leader spots, yet remained fairly inactive. The remaining three numbered sunspot groups are stable or showing signs of decay.
