EVENT LOG: X1.5 SOLAR FLARE     SOURCE: Sunspot 2087
DISCUSSION:

A strong solar flare measuring X1.5 was observed around region 2087 at 12:52 UTC / June 10, 2014. This was the second such event in just over an hour. The event was associated with a Type IV radio emission and a 10cm Radio Burst measuring 530 solar flux units and lasting 18 minutes. A bright coronal mass ejection (CME) became visible shortly afterwards in STEREO Ahead COR2 imagery. Due to the limb proximity, the plasma cloud was directed to the east and mostly away from Earth. A glancing blow may be possible by June 13.

LOG ENTRIES:

Additonal imagery reveals that a glancing blow CME impact will be possible by June 13. Only a slight chance of geomagnetic storming is to be expected.

The WSA-Enlil Solar Wind Prediction model released by the Space Weather Prediction Center has been updated to include the bright CME from this morning following the second X-Flare event (X1.5). As expected, the expansive plasma cloud will likely pass to the east of our planet and have little to no impact on our geomagnetic field.

06/10/2014 @ 15:00 UTC
Initial imagery courtesy of LASCO C3 shows the bright CME heading to the east and away from Earth. Additional imagery still required to determine if a weaker glancing blow is possible.

06/10/2014 @ 14:06 UTC
A bright coronal mass ejection (CME) now visible in the latest STEREO Ahead COR2 imagery beginning at 13:39 UTC Based on the sunspot location, most of the plasma cloud should be directed away from our planet. More updates regarding a possible glancing blow when more imagery becomes available.

AIA video of the event is now available on the right hand side of this page.

06/10/2014 @ 13:30 UTC
The latest event was associated with at TYpe IV radio emission and a 10cm Radio Burst (TenFlare).

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Jun 10 1241 UTC
Maximum Time: 2014 Jun 10 1247 UTC
End Time: 2014 Jun 10 1259 UTC
Duration: 18 minutes
Peak Flux: 530 sfu
Latest Penticton Noon Flux: 161 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 IV Radio Emission
Begin Time: 2014 Jun 10 1230 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.

A strong solar flare measuring X1.5 observed around region 2087 at 12:52 UTC. This is now the second such event in just over an hour. More to follow.
