The flare even caused a shortwave radio blackout.
"Aviators, mariners, and ham radio operators may have noticed unusual propagation effects at frequencies below 30 MHz [megahertz]," the website reported Wednesday in the hours after the flash.Solar flares are ranked first by category — A-class are weakest, then B-, C-, and M-class, with X-class the strongest — and then by size, with smaller numbers representing smaller flares within the class. Wednesday's flare was an X1.3-class flare, according to SpaceWeather.
Flares are outbursts of light, but are sometimes related to coronal mass ejections , which shoot blobs of charged particles out into space. If a coronal mass ejection emerges from the flare and is pointed toward Earth, that could cause, the stunning light shows caused by charged particles hitting Earth's atmosphere. SpaceWeather added that there is circumstantial evidence suggesting a CME is emerging from the sun, but more observations will be required to confirm that.
"A CME is almost certainly emerging from the blast site," SpaceWeather continued, noting that the U.S. Air Force has detected a One of 17 different flares from an active sunspot AR 2975 shines bright in this image from NASA's Solar Dynamics Observatory taken on March 28-29, 2022. apparently generated by a CME leaving the sun's atmosphere," SpaceWeather added.
SDO officially caught imagery of the event at 1:35 p.m. EST , but NASA did not provide a detailed forecast beyond pointing to generic risks that may happen with solar flares. "Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts," NASA officials wrote in a
