A top-class X-flare, recorded almost at midnight on July 1, turned out not to be the most powerful, but it occurred in an extremely unfortunate location for Earth. According to calculations by the Solar Astronomy Laboratory of IKI RAS and ISZF SB RAS, its consequences could reach the planet as early as July 2, from 9:00 PM to midnight Moscow time.

The event received an X1.1 rating – only 10% above the lower limit of the highest category. However, the active centers are now located almost on the Sun-Earth line, so the plasma ejection is heading towards our planet.

The intrigue is that the flare did not occur in the largest region of the year, numbered 4478. It remains calm for now. The source was the smaller neighboring sunspot group 4479, which was the first to release its accumulated energy.

Scientists expect a G3-level magnetic storm – strong, but not extreme. G4 levels and top-category radiation storms are still unlikely, but the upcoming disturbance could be the most significant since March.

The largest region 4478, meanwhile, remains opposite Earth and continues to accumulate energy. Therefore, the current flare may not be the last event in this series.
