M 5.3 + M 2.3 Solar Flares am 4 Juli und steigende Chance von X-Class Flares

CHANCE OF X-FLARES: The chance of an X-flare today is increasing as sunspot AR1515 develops a 'beta-gamma-delta' magnetic field that harbors energy for the most powerful explosions. The sunspot itself is huge, stretching more than 100,000 km (8 Earth-diameters) from end to end. This movie from NASA's Solar Dynamics Observatory shows the behemoth growing and turning toward Earth over the past five days:

If any X-flares do occur today, they will certainly be Earth-directed. The sunspot is directly facing our planet. Radio blackouts, sudden ionospheric disturbances, and geomagnetic storms could be in the offing
