Scientists found that the level of carbon-14, an isotope of carbon, was much higher in rings from that year than usual. Some years later, looking at air samples from ice cores, scientists saw that there were elevated levels of beryllium-10 and chlorine-36 as well.
The common factor in all these elements is that they are created when extremely high-energy subatomic particles hit Earth's air and ground. .... The only way to get particles at energies like this is from space, where powerful magnetic fields in exploding stars...can accelerate the particles to such high speeds.
But the 774 event was so powerful that at first scientists were skeptical it could be from a flare. Once any other type of astronomical phenomenon was ruled out, though, a flare was all that was left
1989 the Sun erupted in a powerful series of flares as well as a huge coronal mass ejection (or CME) Carrying its own magnetic field, this bout of space weather slamme...d into the Earth's magnetic field, affecting it so profoundly that electric currents were induced under the Earth's surface. Called geomagnetically induced currents, this extra electric energy blew out transformers in Quebec and caused a power outage that lasted for hours.
February 1956 was the most powerful solar storm in the modern era, which was easily twice as strong as the 1989 event.
Using various methods to characterize the 1956 storm, including measurements in visible light, radio waves, changes to the Earth's ionosphere (a high-altitude layer of ionized air that, when it changes rapidly, can affect magnetometers on the ground that measure magnetic field strength), and more, they found the 774 AD event was a staggering 30 to 70 times stronger. This means it was likely 100 times stronger than the one in 1989.

Interesting article. Thanks. Strange they don’t mention the Carrington Event.
Curious why he excluded the 1859 Carrington Event? That set telegraph wires and stations on fire, researchers say it penetrated 3 miles into the earth. My measly fire bunker is only six feet down.
At this point, I say bring it on
I had the same thought.
Well that explains the rise of the Vikings................
Ben; Here you be! Coming attractions! Nothing really big expected but good to know.
SOLAR SECTOR BOUNDARY CROSSING: Earth is about to cross a fold in the heliospheric current sheet—a vast wavy structure in interplanetary space separating regions of opposite magnetic polarity. The crossing, called a “solar sector boundary crossing,” is expected on Jan. 10th and could cause geomagnetic activity around Earth’s poles. Aurora alerts: SMS Text.
A mega Carrington event could be a “lets return to grandpa’s time” teaching moment!
Lets hope that when it happens it’s centered on Pakistan and China.
The more important question to ask is “how will this affect our research grant”?
Priorities & all that rot...

Awesome record keeping.
Even found one of my posts on there.
The old memory bank isn’t what it used to be.
The sun has no effect on the earth all. #beleefscyense.
The earliest topic I found just now (as I continued to surf some of the keywords) was from 2003 or so, pretty cool. And I’ve added more kw, [rest of sentence just of of ‘Civ’s redacted b****ing].
The Medieval Warming period drove up food production and population in Scandinavia, but the limits on arable land led to a huge outward expansion. My DNA showed over a quarter Scandinavian, with zero paper trail to support it, but that’s what happens with those of us with British Isles roots and German roots. :^)
The Vikings got around....................
They ruled Sicily for a while, worked for the Byzantine emperors, and of course ruled Normandy, from which William the Bastard launched his invasion of England and usurped the throne.
Well, that’s a good thing, because I can’t speak Norwegian...................
