Here's what that means and how that happens.

The event is courtesy of a solar flare, which erupted out of a sunspot late Thursday into early Friday. This explosion produced what scientists call a "coronal mass ejection (CME)" and it is headed straight for our planet.

A massive sunspot has appeared recently, several times larger than the Earth, which is likely to generate a display of the aurora borealis.

An unusually large release of plasma from the sun is expected to cause a geomagnetic storm when it begins to arrive on Sunday night.

If the storm is strong enough, Washington State could be in for a show, but KIRO 7 Pinpoint Meteorologist Morgan Palmer cautions we won't know for sure until late Sunday evening.

The lights are usually visible in the far northern and southern parts of the world, according to USA Today.

The aurora borealis - the "Northern Lights" - is a region of charged gases in the ionosphere, a region around 50 miles above the earth's surface.

The aurora is caused by electrons colliding with the upper reaches of Earth's atmosphere.

Starting Sunday Night and lasting till Monday Night, a geomagnetic storm watch has been issued! Auroras tend to come in pulses, and don't last long.

For best aurora viewing, it is recommended that sky watchers head to areas far away from city lights. If that is the case, you'll want to quickly get somewhere where it's dark and look up. You may see a faint glow or much more.
