Solar flares are broad energy emissions on the surface of the sun that occur when twisted magnetic field lines
suddenly snap, the phenomenon is characterized by bright flashes on the sun’s surface.
According to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, the sun began unleashing its fury on Wednesday at 5:10 a.m. ET, with an X2.2 flare. Just three hours later, the sun produced a second flare measuring a whopping X9.3—the most powerful on record since 2006.
If a solar flare is directed at Earth, which these ones were, it can generate a radiation storm that interferes with radio and GPS signals. If your devices stopped reporting for a short time on the 7th Sept, this is probably why.
