Big, active sunspot AR3738 is approaching “the danger zone”–a region of the sun magnetically connected to Earth via the Parker Spiral. If the sunspot explodes today or tomorrow, it could send a fusillade of energetic protons spiraling toward Earth. Such “proton storms” can fog cameras on Earth-orbiting satellites and reboot their computers.
