Monopole Super Flare

The Monopole Super Flares are a disaster event that first happened 5 years after Mika Furutsuki's death. They were theorized to be caused by "monopole" magnetic lines, which means rather than having a North and South side, they only had one. This caused great turbulence and caused the sun spots which caused the massive solar flares, up to 10,000 times stronger than a typical solar flare.

Effects
The first monopole super flare didn't hit Earth directly, but it still caused a lot of damage. It cut out all wireless communications across the planet, destroyed the ozone layer, gave everyone on airplanes radiation sickness and killed everyone on the International Space Station.
