EVENT LOG: M8.7 SOLAR FLARE     DATE: 10/22/2014 @ 01:59 UTC     SOURCE: Sunspot 2192

A strong solar flare measuring M8.7 was observed around large sunspot cluster 2192 at 01:59 UTC (Oct 22). The flare did not produce a noteworthy coronal mass ejection (CME). No major impacts to our geomagnetic field are to be expected.

Video presentation of the flare event is now available. Also includes GOES-15 solar X-Rays and Simulated Global D-Layer Absorption data charts.

10/22/2014 @ 02:50 UTC
A Type IV radio emission was associated with the flare event.

ALERT: Type IV Radio Emission
Begin Time: 2014 Oct 22 0215 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.

10/22/2014 @ 02:40 UTC
Based on updated SDO imagery using the 193 angstroms channel, no significant coronal dimming, or shock appears evident. More updates once updated coronagraph imagery becomes available.

A strong solar flare measuring M8.7 was observed around region 2192 at 01:59 UTC (Oct 22). The flare itself was fairly long in duration. Previous flares around this region have yet to yield a noteworthy coronal mass ejection (CME). More updates to follow.

ALERT: X-Ray Flux exceeded M5
Threshold Reached: 2014 Oct 22 0144 UTC
NOAA Scale: R2 - Moderate
Potential Impacts: Area of impact centered on sub-solar point on the sunlit side of Earth. Extent of blackout of HF (high frequency) radio communication dependent upon current X-ray Flux intensity.
