X1.0 solar flare from sunspot region 2192

Saturday, 25 October 2014 18:31 UTC

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.
