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.
