An autumnal equinox-triggered geomagnetic storm is predicted to strike Earth.

A geomagnetic storm may lead to temporary power outages or interference with communication systems.

A geomagnetic storm is predicted to occur on the Earth this week after the autumnal equinox.

On Sunday, a sunspot erupted, resulting in a coronal mass ejection (CME) heading towards Earth.

On Wednesday, it is predicted that the solar plasma, traveling at 650,000 mph, will collide with the magnetosphere, as reported by Space.com.

The occurrence of the CME near the autumnal equinox on Sept. 22 could result in a geomagnetic storm in part of the world.

Geomagnetic storms are more likely during the spring and fall equinoxes because the Earth's magnetic poles align with the sun's.

The geomagnetic storm can sometimes cause disruption in communications or electrical blackouts.

The "Northern Lights" effect can be observed at high altitudes due to the phenomenon.

In June, the aurora borealis was visible in the U.S. and some southern states following a powerful geomagnetic storm.
