a news solar eruption of class M9.6, quite intense, occurred on April 21 at 1:57 UT, ie 3:57 Paris time, again in the active region 2993 and 2994. This time it is more towards Earth.
After a major X1.1 class blowout, Sunday, April 17, in active region 2993 and 2994 (see article below), Sun has just produced the most powerful of his own new cycle of activities started two years ago† Of class X2.2, so much more violent than that of the so-called “Easter”, it appeared on April 20 at 3h57 UT (5h57 Paris time) in the active region 2992, currently on the limb southwest of our Star†
l’archipelago by dark spots, the active region 2992 associated with this event, therefore, shifts on the opposite side of the sun from that opposite the Earth. There may be other powerful eruptions, but they will no longer be visible from our planet and its suburbs. It’s likely, the Spaceweather site notes, that the observed eruption was even more intense, larger than X2.2, given its position relative to us.
A sign that solar activity is intensifying, 19 moderate eruptions were recorded in 24 hours, including a large one. The region 2993-2994, which was the scene of the “Easter Eruption”, in turn orbits Earth.
The count of dark spots since the beginning of the new cyclesymptomatic of its activity, surprises astronomers with their higher numbers than what was predicted by their models.
An intense solar flare caused radio interference

l’activity of our sun† It has certainly been talked about very regularly in recent weeks. And still today. Because the American Center for weather forecast (SWPC) recorded a class X solar flare at exactly 5:34 am Paris time this Sunday, April 17, 2022.
Today’s X-1.1 flare is probably just the beginning for this complex set of sister regions. 2993 & 2994 are already visible. Soon another one (old region 2976) will be added!

Recall that solar flares are classified according to the maximum intensity of their energetic flux in categories A, B, C, M and X. Class X eruptions are the most intense.
The so-called eruption ” by Easter† took over half an hour. And it was followed by an ejection of mass coronal (CME† Resulting in a short black out radio in Asia and Australia. A black out short expensive due to the shock waves appearing in the leading edges of the CMEs. Because it wasn’t aimed directly at Earth.
Indeed, the result appeared in a group of sunspots active on the eastern part of the sun. But the astronomers expect even more intense activity in the coming days as these spots move along the Earth’s side of our star.
