Sunspot region 2192 (now the largest sunspot region in 24 years) produced a major X3.19 solar flare (R3-strong radio blackout) at 21:41 UTC. This was the third and also the strongest X-class solar flare from this sunspot region and the sixth strongest solar flare of the current solar cycle.
Coronagraph imagery is not yet available to confirm the launch of a coronal mass ejection but the lack of any significant coronal dimming (traces in the solar corona of ejected material) suggests there might not be a major coronal mass ejection associated with this event despite the long duration of the solar flare. This solar flare looks pretty similar to the previous X-class solar flares that also failed to launch a coronal mass ejection.
The magnetic loops holding this group together just do not want to break and release a coronal mass ejection it seems, just like all other previous solar flares (excluding today's M-class solar flare) also failed to produce coronal mass ejections. This is a shame as sunspot region 2192 is now in a great position for any eruptions to be earth-directed but we do need to wait for coronagraph imagery from SOHO to be 100% sure that there is again no or only a minor coronal mass ejection. This post will be updated as soon as more information becomes available so keep checking back.

ALERT: X-Ray Flux exceeded M5 Threshold Reached: 2014 Oct 24 2113 UTC NOAA Scale: R2 - Moderate

Here is the latest coronagraph image from SOHO/LASCO C2 showing... nothing.
As expected, the X3.1 solar flare is not eruptive and no coronal mass ejection was launched. Sad news for aurora lovers around the world but it is how it is!
