Two X-ray flares occurred on the Sun in one day

Two X-class flares observed on April 24, 2026

The increasing solar activity, as predicted the day before, has surpassed the threshold for high-level solar flares. Two X-level solar flares were recorded within 24 hours. The first was observed at 1:07 UT. The second event occurred exactly 8 hours later, at 9:07 UT. Both events had nearly identical magnitudes, approximately X2.5, and were the most powerful in almost 2.5 months. A larger flare, X4.2, was last recorded on February 4th, amid an exceptionally powerful series of solar events that occurred during those days, ultimately becoming the most powerful of this century.

Both flares were accompanied by large plasma ejections, clearly visible in images received from space telescopes. However, the origin of the explosions was significantly shifted toward the Sun's limb (the angle to Earth is more than 60°), and even the naked eye can see the plasma escaping sideways. For this reason, there was initially a high probability that both events would be neutral for Earth. Mathematical modeling currently confirms this conclusion. In any case, frontal impacts are definitely excluded in such a situation, and the probability of weak impacts on the planet by the edge of the plasma cloud can be neglected.

There are currently no signs of a decline in activity. New major events are possible.
