EVENT LOG: M5.2 SOLAR FLARE     SOURCE: Sunspot 2056

A moderately strong solar flare measuring M5.2 was observed around sunspot 2056 peaking at 10:07 UTC. The event generated a 10cm radio burst measuring 390 sfu and lasting 8 minutes. The active region is not yet in the best position for Earth directed coronal mass ejections. At this time, a large CME does not appear to be associated with the flare.

Additional coronagraph imagery confirms that a CME was not associated with the event. No impact to our geomagnetic field is expected.

Additional video of the flare event is now available.

05/08/2014 @ 12:10 UTC
As of this update, new imagery by STEREO Behind COR2 does not show a CME as of yet. The flare itself was fairly impulsive, so a large CME is not likely. Further updates to follow when necessary.

The solar flare event was associated with a 10cm Radio Burst (TenFlare) measuring 390 solar flux units (SFU) and lasting 8 minutes.

SUMMARY: 10cm Radio Burst
Begin Time: 2014 May 08 1000 UTC
Maximum Time: 2014 May 08 1002 UTC
End Time: 2014 May 08 1008 UTC
Duration: 8 minutes
Peak Flux: 390 sfu
Latest Penticton Noon Flux: 146 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.

A moderately strong solar flare measuring M5.2 was just observed around sunspot 2056 peaking at 10:07 UTC. More details to follow.
