In pictures: Northern lights make a rare southern appearance

A powerful geomagnetic solar storm has made the northern lights visible much farther south than usual.

CMEs are explosions of plasma and magnetic fields from the sun’s corona. When directed at Earth, they cause geomagnetic storms.

The CME travelled to Earth at nearly 1.5 million miles per hour (2.4 million kilometers per hour), according to NOAA’s Space Weather Prediction Center (SWPC).

In May, the planet went through the most powerful geomagnetic storms recorded in 20 years. They caused auroras to light up the night sky in the United States, Europe, and Australia, at much lower latitudes than usual.

This type of event has increased recently because the Sun is currently close to its peak activity, as per its 11-year cycle.

Such intense geomagnetic activity can cause other, less savory effects.

Communications signals that must pass through the upper atmosphere are subject to distortion and can become unreliable. This includes GPS and many global systems used for shipping.
