The solar flare, classified as M8 in the second-most energetic category of flares, departed from the sun at 5:49 a.m. EDT (0949 GMT) on Friday, disrupting shortwave radio communications in the sun-facing parts of the world. According to Spaceweather.com(opens in new tab), amateur radio operators in Africa and the Middle East could have experienced signal distortion for up to one hour after the flare.
The U.K. space weather forecaster Met Office predicts there is a chance of further flares today before the sunspot AR3098 disappears behind the sun's limb (the edge of the sun's visible disk). Space weather forecasters think a coronal mass ejection (CME), a burst of charged plasma from the sun's upper atmosphere, the corona, may have accompanied the flare and might be heading toward Earth. If so, the planet might experience a geomagnetic storm later in the weekend, the Met Office said in a statement(opens in new tab).

Just as well. Radio is cultural appropriation, anyway
No, it didn't. We'd still be waiting on it.
If it struck on Friday it left the sun days before.
A CME would take days, but a solar flare would take 8 minutes.
My bad.
After all these yrs of saying it could happen, it finally did. What are the odds?
Solar flares are racist
Dang it! And I was expecting my password from the Nigerian prince yesterday to put that money in my account. Oh, well. Guess that $20,000,000 wasn’t meant to be after all.
You were correct the first time. Light takes 8 minutes from the sun. You can see the flare in minutes but the mass from it that affects comms on Earth takes days.
More on yesterday’s flare at link below. Interesting info on Starlink satellites / failures further down in the article....
THE STARLINK INCIDENT: A minor geomagnetic storm is supposed to be minor. That’s why even experts were surprised on Feb. 4, 2022, when dozens of Starlink satellites started falling out of the sky. A weak CME had hit Earth’s magnetic field, and the resulting G1-class (minor) storm was bringing them down:
How could this happen? A new paper published in the research journal Space Weather provides the answer.
“Although it was only ‘minor,’ the storm pumped almost 1200 gigawatts of energy into Earth’s atmosphere,” explains lead author Tong Dang of the University of Science and Technology of China. “This extra energy heated Earth’s upper atmosphere and sharply increased aerodynamic drag on the satellites.”
SpaceX launched the satellites from Cape Canaveral on Feb. 3, 2022. Forty-nine (49) Starlinks were crowded inside the Falcon 9 rocket; less than a quarter would survive.

And I was wondering where that extra $20,000,000 came from in my savings account. Now I guess the bank will NOT want the money back.
Instead of a prop plane down at the Hangar, I guess it will be OK to finally upgrade to a jet. And that should be enough to pay for the fuel for a few years....
