Quick answers

What is a G2 geomagnetic storm?

A G2 geomagnetic storm is a moderate-level geomagnetic storm that can cause fluctuations in power grids and impact satellite operations. It can also enhance the visibility of the northern lights.

What is a CME?

A coronal mass ejection (CME) is a significant release of plasma and magnetic field from the solar corona. When directed towards Earth, it can interact with the planet's magnetosphere, potentially causing geomagnetic storms.

What is an X-class solar flare?

An X-class solar flare is the most intense type of solar flare. X-class flares can cause radio blackouts and other disruptions on Earth.
