Increased solar activity causes auroras that dance around Earth’s poles, known as the northern lights, or aurora borealis, and southern lights, or aurora australis. When the energized particles from coronal mass ejections reach Earth’s magnetic field, they interact with gases in the atmosphere to create different colored lights in the sky.

Northern Lights may dazzle again tonight as a severe geomagnetic storm reaches peak intensity across regions. Follow live.

The last in a series of three coronal mass ejections hit Earth on Wednesday, so experts are keeping an eye on geomagnetic storm potential

The sun has burped out bursts of energy called coronal mass ejections that could reach Earth Tuesday night. Forecasters said the vibrant displays could be visible across much of the northern U.S.

Experts at NOAA recommend prospective aurora viewers travel north, towards the Earth’s magnetic north pole. They should position themselves on a vantage point with a clear view towards the north, and away from bright city lights. The aurora is most active in the hours around midnight, so viewers should plan to watch between 10 p.m. and 2 a.m.

Australia and New Zealand witnessed a spectacular aurora australis, a 'cannibal' solar storm causing vibrant pink, violet, and green lights. This G4 g
