After a series of eruptions on the Sun, Earth may be in for auroras over the next few days.
of which our Sun is capable, but plenty strong enough for its effects to be felt here on Earth.
For both flares, a burst of X-rays ionized the top of Earth's atmosphere, causing brief, minor short-wave radio blackouts; the first above South America and the second over the Indian Ocean. Coronal mass ejections , which are caused by magnetic field lines snapping and reconnecting, are massive ejections of up to billions of tons of plasma from the solar corona, carrying an embedded magnetic field. These often occur in concert with solar flares, and travel outwards from the Sun, taking several days to arrive at Earth if they're heading in our direction.If they're not, they can still deliver a glancing blow. That's what we might see with the two CMEs from AR2929.
We might also see auroras, when charged particles from the CME collide and interact with Earth's atmosphere and magnetic field to produce gorgeous light shows at high latitudes.This cycle is based on the Sun's magnetic field, which flips every 11 years, with the north and south magnetic poles switching places. It's not known what drives these cycles , but the poles switch when the magnetic field is at its weakest, also known as the solar minimum.
