  Fucking enough “slams” in headlines!!!¹¹11one. /s

  The abundance of back-to-back solar events has led scientists to think the sun may have entered its explosive era of peak activity, known as solar maximum — which seems to be starting a year earlier than previous forecasts predicted. However, researchers will have to wait until the sun “calms down” to know for sure.

  What we do know is that X-class flares are most common during solar maximum, which is part of the sun’s 11-year solar cycle. So far in 2024, seven X-class flares, including the latest one, have burst from the sun, which is already half the number that reached Earth in 2023, Live Science previously reported.

  On a long enough timescale, we’re gonna be hit by a big one.

  I remember like a decade ago they were saying it hits a developed area, it’ll blow out all the transformers, and on that scale no country could replace them all for a very long time.

    I believe it’s possible to avoid if the proper protocols are in place. Namely, the grid has to be turned off completely before the flare hits and then things will mostly be fine. Just wonder how well we can predict these events.

      My understanding is that we actually don't have much of a warning (under an hour), since a CME has to reach the satellite at the Lagrange point between Earth and the Sun for us to know it's about to hit Earth. According to the article below, this includes power companies, but I remain skeptical that there's enough organisation in place to shut down the North American, European or Asian grids in 15 minutes.

    I agree. There were articles and documentaries about 20 years ago that I remember featuring these sort of events. The continent affected would take 20-30 years to rebuild its electricity grid.

      I’ll just never get over how “we” (science I guess) know that stuff like this isn’t a question of if, but when.

      And we just don’t seem to get ready for it.

      Like, Y2K we saw coming and everyone handled it in time. But if there’s no firm date on something, everyone with the power to do anything just ignores it.

      As a society it just feels like we’re living paycheck to paycheck. Can’t worry about next year cuz rents due in two weeks shit.

      It’s just not a good way to go about things.

    We have certainly been hit.

      …

      Yes, we get hit by them all the time…

      What everyone else is talking about is a big one.

  This is the best summary I could come up with:

  ---

  On March 28, Earth was hit by an X-class solar flare that was strong enough to ionize part of the planet’s atmosphere.

  Scientists spotted the solar flare erupting from the bottom of the sun on Thursday (March 28), using satellites from the National Oceanic and Atmospheric Administration (NOAA), according to the organization’s Space Weather Prediction Center.

  The explosion was so powerful that it ionized the top of Earth’s atmosphere, resulting in a “deep shortwave radio blackout over the Pacific Ocean,” SpaceWeather.com reported.

  NOAA scientists were initially concerned that the CME would collide with Earth, potentially resulting in a geomagnetic storm that could impact satellites, radio communications and other infrastructure.

  This solar event comes on the heels of a “double” X-class flare that occurred Monday (March 25), triggering the most powerful geomagnetic storm on our planet in six years.

  So far in 2024, seven X-class flares, including the latest one, have burst from the sun, which is already half the number that reached Earth in 2023, Live Science previously reported.
