A massive, “full-halo” solar storm is headed towards Earth, and is due to hit our atmosphere on July 23.
According to SpaceWeather.com, a solar tsunami eruption on July 21 flung a cloud of solar plasma and other solar particles in our direction, and when they hit the Earth, they will cause geomagnetic storms.
When twisted magnetic field lines on the Sun suddenly reconfigure themselves, the Sun spits out huge plumes of plasma.
The matter ejected from the sun in a CME can contain billions of tons of particles from the sun’s atmosphere and also carry an embedded magnetic field: large and fast CMEs can travel at speeds of up to 4.5 million miles per hour.
CMEs are normally harmless to humans, as the majority of the time they aren’t pointed at Earth.
The “full-halo” CME that occurred on July 21 is, however, expected to hit the Earth’s magnetic field. Halo events are so-called because of the way they appear in coronagraph imagery, seemingly flaring out around the sun like a halo.
