Massive Solar Storm Coming 2025 Solar Storm. During solar maximum (left), the sun's magnetic field weakens, allowing more sunspots to appear and unleashing more solar storms than during solar minimum (right). Another strong geomagnetic storm (g4 or above) is possible in 2025.
A slight chance for an s1 (minor) solar radiation storm event will persist through 05 jan given the current total disk potential and as ar 3939 approaches the western limb. Solar flares and coronal mass ejections (cme) will likely become more probable.
