Residents of the northern United States can see a dawn on Saturday night

Some of us, the Terrans, can see dancing, green lights in the sky on Saturday night.

On March 20, the sun projected a torch of energized particles into space, and the National Ocean and Atmospheric Administration's (NOAA) space prediction center predicts that a band from the north of the United States could to undergo a visible effect of this event: a dull greenish dancing light, created when the particles of the sun interact with the Earth's atmosphere.

Such an atmospheric event is fueled by a disturbance called a geomagnetic storm, where activated solar particles cause changes in the Earth's magnetosphere – a vast spatial area around the Earth where the planet's magnetic field changes and evolves in reaction to the sun.

It often takes a few days for powerful solar flares, called coronal mass ejections (CME), to strike the Earth and fuel a space storm.

The Space Prediction Center predicts that a curved strip of land between Washington and Maine in the United States is the "most likely" extension of celestial lights, although areas as far south as Colorado may be treated like auroras.

This extension should be between the green and yellow lines of the NOAA graph above, or the tweet below. This concerns parts of Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Iowa, Michigan, Wisconsin, Illinois, New York, Vermont, New Hampshire and Maine.

Although the Lower 48s may have a green light, the event should be quite keen on most of Alaska, where the dawn epicenter will be impressively exposed on a ring at the top of the planet.

To see the lights, it is best to look in the darkest possible night sky away from light pollution and, if possible, before the moon rises.

Good celestial visualization.
