Scientists say that on Thursday, the Sun issued a significant solar flare toward Earth, peaking at 11:35 a.m. EDT.

Solar flares are powerful bursts of radiation and, although harmful radiation from flares cannot pass through Earth’s atmosphere to physically affect humans, when they are intense enough they can disturb the atmosphere in that layer. Where GPS and communication signals travel.

The flare was classified as a x1, with the X-Class being the most intense. X10 flares are considered unusually intense.

This was the second X-Class flare of Solar Cycle 25, which debuted in December 2019.

two more explosions Involves the explosion of solar material known as a . is called coronal mass ejection And an invisible swarm of solar energy particles that had drifted toward Earth, Goddard said.

coronal mass ejection Large clouds of solar plasma and embedded magnetic fields are released into space after a solar eruption. NASA Note That the fastest Earth-directed coronal mass ejection could reach our planet in as little as 15-18 hours.

The particles collide with Earth’s magnetic shield and can create a type of space weather known as a geomagnetic storm.

“One of the most common forms of space weather, a geomagnetic storm refers to any time Earth’s magnetic environment, the magnetosphere, undergoes sudden and repeated changes,” explains NASA Science. “Geomagnetic storms can be caused by high-speed bursts of the solar wind and when a CME attaches to the magnetosphere. The Sun’s magnetic field peels off the outermost layers of Earth’s regions, changing the shape of the magnetosphere. Magnetic storms are measurable.” worldwide, such as radio communications blackouts and power grid failures.”

National Oceanic and Atmospheric Administration Space Weather Prediction Center said on Friday A Geomagnetic Storm Watch is in effect this weekend.

The impact on technology from such storms is generally nominal, but has the potential to further push auroras away from their normal polar habitat, the center said.

aurora The display of light in the sky typically occurs in the northern and southern regions that occur when charged particles from the Sun collide with oxygen and nitrogen in Earth’s atmosphere about 60 to 200 miles away, creating a wave of light and heat. Flash goes out.

Electrons and protons released by solar storms can form bright auroras at lower latitudes.

Because of the latest flashes, the Northern Lights may be visible in the far Northeast, upper Midwest, and Washington State – although it may be difficult to see if you live near city lights.
