Keep your fingers crossed for clear skies: the U.S. Space Weather Prediction Center (SWPC) is calling for a strong geomagnetic storm, which could produce the northern lights.

Typically, we get the northern lights after a strong solar flare, w here the magnetic fields get entangled and then snap, releasing intense bursts of radiation, which can disrupt high-frequency radio signals here on Earth.

The flare is usually followed by a coronal mass ejection, or CME. The CME is a fast-moving stream of particles burped out by the sun that travels very fast along the solar wind.

If Earth is in its path, the particles interact with our magnetic field and molecules in the atmosphere, providing a beautiful light show in the sky.

There were three CMEs unleashed over the past two days. Two will give
