Solar proton event seen in paleo records (Carbon 14 in Tree Rings)

I don’t recall hearing if anything similar was noted about the Carrington flare.

[Deathtomarxists]

That explains all the crazyness that erupted at that time.

What is CE?

[DannyTN]

Doesn’t most Carbon-14 dating depend on the assumption of a constant level of production of Carbon-14 in the atmosphere. It also depends on no groundwater leaching of carbon-14 into or out of the sample.

Coronal Ejection or maybe Coronal Explosion.

Terminology used by Solar Scientists.

See:

Coronal mass ejection

[Psalm 73]

"What is CE?"

That's "A.D." for athiests.
(CE = "Childish Enlightenment")
They can't bring themselves to admit that Jesus Christ is the center of human history.

[Psalm 73]

Sure - I know EC stands for “Common Era”, as BCE stands for “Before the Common Era”

[Ernest_at_the_Beach]

Maybe Coronal Event....

[Ernest_at_the_Beach]

Could be Carbon Enhancement.....

[norwaypinesavage]

"such an event would have severely damaging effects on the technology on which society relies."

Oh Noes! This means we'll have to give up SUVs and increase taxes and the size of government, and give up on gasoline.

From the link at #9:

could explain the 774-775 CE carbon-14 enhancement.

[Ernest_at_the_Beach]

Leftie politicians will be right on that very soon.

Thank you everyone.

CE = Christ Era
BCE = Before Christ Era

ScienceShot: What Struck Earth in 775?

In 775 C.E., while Charlemagne was ruling his Frankish kingdom, something mysterious struck Earth. An analysis of the rings of two Japanese cedar trees (typical tree rings shown above), reported online today in Nature, reveals that from 774 to 775 C.E., the atmospheric level of radioactive carbon-14 jumped by 1.2%. This indicates that cosmic rays—high-speed, charged particles from space—bombarded our planet and converted some atmospheric nitrogen-14 into carbon-14. Earlier work had found a rise in radioactive carbon during the same decade; the new discovery means that scientists have been able to narrow down the date of impact to within just 1 year. The scientists argue against two logical suspects: solar flares are too weak to do the job, and no supernova explosion was seen at the time, nor do any nearby supernova remnants date back to Charlemagne's time. There's also nothing unusual in the history books. So the cause remains a mystery, but whatever it was, something similar could presumably strike again.

I should have read the rest of the thread before posting.
There are many answers : )

[ModelBreaker]

I call it “Christian Era.”

You were being helpful, that’s good by me. :)
