The Sun experienced its strongest flare in 1.5 months.

An M9.3 solar flare on June 3, 2026

At 01:36 UT, a solar flare of M9.3 magnitude was recorded. According to catalogs, this is the strongest since April 24, 2026, when two high-level X-class explosions occurred within 24 hours. In this case, the solar flare activity fell short by about 7%. The solar situation began to worsen yesterday afternoon, when the solar flare activity graph, which had previously been a straight line, began to resemble an electroencephalogram. Putting aside physics, which is currently of no help, and simply looking at the graph as a mathematical curve, we can see that the flares are occurring at a roughly constant rate of about 7 hours, with increasing intensity. Therefore, the next one should occur around midday at a level above X-class. Physical models, however, continue to insist that, given the current configuration, strong solar flares are virtually impossible, and estimate the probability of an X-class explosion at 3%.

The flare occurred almost exactly at the center of the Sun, where plasma clouds ejected from the epicenter have nowhere else to go but toward the blue planet Earth. However, objective monitoring has not yet confirmed the plasma emission. For now, the flare is considered harmless. So, we'll see what happens throughout the day.
