The Solar Astronomy Laboratory of IKI RAS recorded the strongest solar flare in the last month and a half. The M9.3-class event occurred on June 3 at 04:36 Moscow time. It was about 7% short of the highest, X-ray class X. Previous powerful X-class explosions were observed on April 24, 2026.
The flare was registered almost exactly at the center of the solar disk. This means that if a plasma ejection had occurred, it would have been directed straight at Earth. However, according to objective monitoring data, the ejection itself has not yet been recorded. Scientists consider the flare harmless.
The situation on the Sun began to worsen the day before. The flare activity graph, which had previously been almost a straight line, sharply went up. Flares follow at intervals of about seven hours, and their intensity is increasing. Physical models, on the contrary, estimate the probability of an X-class explosion at only 3%, claiming that with the current configuration of magnetic fields, strong events cannot occur.
Nevertheless, if the observed rhythm continues, the next flare could occur around noon — and then it will likely cross the X-class threshold. Specialists continue to monitor the situation.
