X2.0 solar flare from sunspot region 4001
Sunday, 23 February 2025 19:55 UTC
It has been 53 long days but we have finaly seen another X-class solar flare coming from the Sun today. Sunspot region 3947 produced an X1.8 solar flare on 4th of January and since that day... silence... but today departing sunspot region 4001 produced an X2.0 solar flare.
The solar flare was impulsive and unfortunately from a location pretty much behind the north-west limb so do not expect any earth-directed coronal mass ejections. Even a solar radiation storm is unlikely due to the impulsive nature of the event.
