X1.0 solar flare from sunspot region 2192

X1.0 solar flare from sunspot region 2192

Sunspot region 2192 did it again! Less than 24 hours after the major X3.19 solar flare from yesterday, it now produced a major X1.04 (R3-strong radio blackout) solar flare at 17:08 UTC. This was already it's fourth X-class solar flare but again it looks like it did not launch a coronal mass ejection.

SDO/AIA 94 Ångström

SDO/AIA 1600 Ångström

SDO/AIA 193 Ångström

SDO/AIA 304 Ångström

 

This solar flare looks very similar to the previous X-class solar flares. 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.
