The US could see the Northern Lights tonight

USA TODAY

Displays of the northern lights—also called the aurora borealis—are possible on Monday evening in northern U.S. states as an incoming coronal mass ejection from the sun was detected arriving at Earth.
The raging aurora seen across the world at lower latitudes on and around May 10 was caused by a G5 geomagnetic storm.
The G2 geomagnetic storm predicted for tonight is “moderately intense” and means an auroral oval around the north pole that won’t reach as far south.
According to the SWPC, the U.S. states on or above the viewline—a prediction of the intensity and location of the aurora borealis—comprise Washington, northern Idaho, Montana, North Dakota, northern South Dakota, Minnesota, Wisconsin, northern Michigan and northern Vermont, northern New England and northern Maine.
The viewline represents the southernmost locations where you may see the aurora on the northern horizon tonight.
If you’re in one of these states and want to see aurora tonight, get away from light pollution and remember that the short hours of darkness will restrict the viewing window.
The aurora was seen across the world on May 10 was the strongest geomagnetic storm for 21 years, with northern lights seen as far south as Arizona and Florida.
The CME arriving at Earth tonight is from the same sunspot region—now called AR3697—that caused May 10’s geomagnetic storm.

POSITIVE

Monday evening in northern United States is a possibility for displays of the northern lights, also known as the aurora borealis. s. describes the detection of an incoming coronal mass ejection from the sun that is headed toward Earth.

A coronal mass ejection (CME) is the sun’s outpouring of charged particles and magnetic fields that can reach speeds of up to 1,900 miles per second (3,000 kilometers per second). Although it can take several days for light to travel from the sun to Earth, it is difficult to estimate the precise time of arrival.

According to an agency post on X, the NOAA Space Weather Prediction Center called for a “G2 Geomagnetic Storm Watch” yesterday, and it is still in effect today.

U. s. States Along The “Viewline”.

The solar wind can produce geomagnetic storms, though G2 storms are not the strongest. On and around May 10, a G5 geomagnetic storm was responsible for the violent aurora seen throughout the world at lower latitudes. Tonight’s “moderately intense” G2 geomagnetic storm is expected to create an auroral oval around the north pole that won’t extend as far south.

As per the SWPC, the U. S. States included in this category are Washington, northern Idaho, Montana, North Dakota, northern South Dakota, Minnesota, Wisconsin, northern Michigan, and northern Vermont, as well as states on or above the viewline, which is a forecast of the aurora borealis’ intensity and location. There should be an aurora display over most of Canada.

The southernmost points where you might be able to see the aurora tonight on the northern horizon are represented by the viewline. If you live in one of these states and would like to see the aurora tonight, avoid light pollution and keep in mind that the viewing window will be limited by the short amount of darkness.

The Reason Behind The Aurora.

The charged solar particles known as aurora are accelerated down the Earth’s magnetic field’s field lines by the solar wind in space. Hundreds of miles above the surface, they take place in the ionosphere of Earth.

On May 10, the world witnessed the strongest geomagnetic storm in 21 years, resulting in the sighting of the northern lights as far south as Arizona and Florida. Red and extremely uncommon blue auroras were seen over much of Europe and North America.

The geomagnetic storm on May 10 was caused by the same sunspot region, which is now known as AR3697, from which the CME that is coming to Earth tonight originates.

“Solar Maximum” is about to happen.

With 171 sunspots observed in May, it was the sun’s busiest month in decades. Solar flares and CMEs originate from sunspots, which are magnetic disturbances on the sun’s surface that can sometimes be as large as Earth. The reason for the sun’s extreme activity is that it is almost at “solar maximum,” which the SWPC says will happen this year. The sun goes through a waxing and waning solar cycle that lasts about 11 years.

Around the North Pole, at latitudes between 66 and 69 degrees north—the Arctic Circle—the northern lights are typically visible as an auroral oval. Northern Russia, Iceland, Greenland, Norway, Sweden, and Finland are the best places to see them, along with Alaska and northern Canada.
