X2.0 solar flare from sunspot region 2192

X2.0 solar flare from sunspot region 2192

...and that is number five! Sunspot region 2192 again produced a major solar flare: X2.01 (R3-strong radio blackout) at 10:56 UTC. This was already it's fifth X-class solar flare and the 13th strongest solar flare of this solar cycle... however... just like all the other X-class solar flares that we have previously seen from this sunspot region... it again looks like it did not launch a coronal mass ejection.

I am afraid that the text here is going to look very similar to the text from our previous articles because this solar flare again does not seem to be an eruptive event. It looks exactly like all the other previous X-class solar flares from sunspot region 2192. While coronagraph imagery is not yet available to confirm the launch of a coronal mass ejection, we can again conclude that due to the lack of any significant coronal dimming (traces in the solar corona of ejected material) there might not be a major coronal mass ejection associated with this event despite the long duration of the solar flare.

This post will be updated as soon as more information becomes available so keep checking back.
