Mysterious radiation burst recorded in tree rings
Nature ^ | Sunday, June 3, 2012 | Richard A. Lovett

Posted on 06/04/2012 10:58:45 AM PDT by SunkenCiv

Just over 1,200 years ago, the planet was hit by an extremely intense burst of high-energy radiation of unknown cause, scientists studying tree-ring data have found.

The radiation burst, which seems to have hit between AD 774 and AD 775, was detected by looking at the amounts of the radioactive isotope carbon-14 in tree rings that formed during the AD 775 growing season in the Northern Hemisphere. The increase in 14C levels is so clear that the scientists, led by Fusa Miyake, a cosmic-ray physicist from Nagoya University in Japan, conclude that the atmospheric level of 14C must have jumped by 1.2% over the course of no longer than a year, about 20 times more than the normal rate of variation...

The only known events that can produce a 14C spike are floods of γ-rays from supernova explosions or proton storms from giant solar flares. But neither seems likely, Miyake says, because each should have been large enough to have had other effects that would have been observed at the time.

A massive supernova, for example, should have been bright enough to produce a 'new' star visible even in the daytime, as was the case for two known supernovae in AD 1006 and AD 1054. Such an explosion would have needed to be brighter than either of these, Miyake says, because those events were not large enough to leave traces in the 14C record.

It is possible, he says, that the proposed event might have occurred in the far southern skies, where astronomers of the era wouldn't have seen it. But still, he says, if it did happen, today's X-ray and radio astronomers should have found signs of a "tremendously bright" remnant of the explosion.

In before that "give me a nice fat grant please" idiocy begins. Extra to the APoD list.
In the late eighth century, Earth was hit by a mystery blast of cosmic rays, according to a Japanese study that found a relic of the powerful event in cedar trees. Analysis of two ancient trees found a surge in carbon-14 -- a carbon isotope that derives from cosmic radiation -- which occurred just in AD 774 and AD 775, the team report in the journal Nature on Sunday. Earth is battered by protons and other sub-atomic particles which are blasted across space by high-energy sources. The particles collide with the stratosphere and react with nitrogen to create carbon-14, which is then absorbed into the biosphere. A team led by Fusa Miyake of Nagoya University found that levels of carbon-14 in the two cedars were about 1.2% higher in 774 and 775 compared to other years... the cosmic whack of 774-775 cannot be attributed to the Schwabe cycle of the time -- and it is far bigger than any known flare from the Sun. The other possibility is a supernova, or a star that explodes at the end of its life in a welter of gamma radiation. They intend to fine-tune the search for the source by looking at telltale traces of beryllium and nitrate isotopes. They also plan a wider search of historical documents to see if, 1,237 years ago, anyone noted a strange flare in the sky.

No account has survived. The Crab Nebula formation was in the 11th c, and there's a record of that (Chinese court, perhaps others?), but no trace of a similar elevation in the tree rings. Whatever it was, must have rung some bells. And the best part, crud from the blow-up will take longer to get here than the cosmic rays, but it will get here. :'o
A Celestial Collision
by Larry Gedney
February 10, 1983
Early in the evening of June 18, 1178, a group of men near Canterbury, England, stood admiring the sliver of a new moon hanging low in the west. In terms they later described to a monk who recorded their sighting, "Suddenly a flaming torch sprang from the moon, spewing fire, hot coals and sparks." In continuing their description of the event, they reported that "The moon writhed like a wounded snake and finally took on a blackish appearance"... [P]lanetary scientist Jack Hartung of the State University of New York... gathered enough clues to suggest that a large asteroid... might have smacked into the moon just over the horizon on the back side. To test his suspicion, Hartung went to the Lunar and Planetary Institute in Houston, and inspected Russian and American photographs of the moon's back side. Sure enough, in just the right place, he found a remarkably fresh crater, 12 miles across and twice as deep as the Grand Canyon. From it radiated white splatter marks for hundreds of miles... Such an impact, reason astrophysicists, would set the moon to ringing like a gong for thousands of years... At Texas' McDonald Observatory, astronomers Odile Calame and J. Derral Mulholland of the University of Texas find that the surface of the moon moves back and forth fully 80 feet! Such an oscillation clearly implies a collision with something large, sometime within the not-too-distant past, probably within the memory of mankind. The problem is that there is no way to peg the date exactly at 1178.

“The radiation burst, which seems to have hit between AD 774 and AD 775”

Were they prototyping the Fukushima Daiichi reactors then?

It is probably more proof that "more happened at Fukushima than we were told", and that "an eeeeevvilllll corporation only concerned with profits" (i.e., TEPCO) is just lying and covering it up. What really happened was that Fukushima melted down into the center of the earth and combined with all the uranium down there and made a mini-black hole that caused a time warp and sent all of Fukushima's radiation in to the past and caused that excess 14C we are seeing in those tree rings. Yeah, that's it. And we have a "scientific study) to prove it, and I am sure that people like Robert Alvarez and Arnie Gunderson and Helen Caldicott and Amory Lovins will probably be getting ready to verify it. And when that mini-black hole breaks through to the other side of the Earth, you know what that means:

We Are All Going To Die

Not, at least, from where it could have been seen from the northern hemisphere, which is where much of the remembered astronomy was happening.

It might be interesting to research some of the mythology or remembered lore of southern hemisphere peoples to see if anything might be connected.

I took the year 774 AD and searched for disruptions, which might indicate a successful society experiencing a sudden intense struggle for survival. Famine during the Dark Ages was an all too common occurrence. However, when a very successful nation-state experiences political upheaval, it's most often due to a protracted famine like these researchers insist would follow a supernova, or a CME.

The fascinating results include the demise of the Viking founded nation of Lombard, which recorded ten years of unprecedented instability beginning in 774 AD and ending only when Charles the Great, Charlemagne, the First Holy Roman Emperor took control of Lombard. Why does this matter to you and I living during the 21st Century? Without the defeat of the hardy Viking Kingdom of Lombard and the rise of Charlemagne there might never have been a Roman Catholic Church and the Renaissance might look a whole lot different to us today. Charlemagne, most importantly secured the safety of the Papacy in Rome for all time. The rise of the Judeo-Christian West was assured and Almighty God is still in complete control of His-story!

Image above: Ground based Observation by W.M. Keck Observatory: The location of the gamma-ray burst as determined by the Swift X-Ray Telescope (XRT) is shown by the blue circle on this infra-red image of the sky from the W.M. Keck telescope. The burst went off in the outskirts of this huge galaxy 2.6 billion lights years away. The location outside, but near, the galaxy fits perfectly with the theory that short bursts are due to black hole formation when orbiting neutron stars collide. The gamma-ray source has not yet been securely identified and scientists are most interested in the 4 objects within Swift's X-ray telescopes error circle. Click on image to enlarge.

So how has this rather puny looking Picea abies lived so long? Its ability to grow a new trunk when the old one dies is the main reason.

Ha ha. Yeah, baby, zeta-pinch aurora. Too bad the one proposed for the late Stone Age/early Bronze Age doesn't have representative tree ring data from 10,000 BC, though it should be possible to see chemical evidence of the huge proton influx in Greenland ice cores.

Is carbon-14 used for dating ?

Yes

If so, would such bursts cause skewing in results?

Yes. The Theory behind carbon-14 dating relies on a constant rate of upper atmosphere 14C generation, based on a constant flux of solar protons converting nitrogen-14 to carbon-14.

The Practice attempts to compensate for variations in proton flux by 14C dating samples of know ages and making a table of 14C dates Vs calendar dates.

This is further complicated by plants having species specific varying rates of 14C uptake.

The upshot?

Carbon-14 data provides a fairly accurate estimate of age, providing the sample isn't so old that all the 14C has decayed.

To: null and void

How does the existence of additional carbon-14 affect dating? Do objects absorb new amounts from the burst? Do objects with carbon-14 convert slower if atmosphere contains more carbon-14?

Wondering about the process.

I get the estimating is pretty accurate, but wonder about the variables. Do these known and unknown variables have a significant +- range that causes dating to be within decades/centuries etc as we go further back in time without less corresponding data points? Could local conditions have significantly different rates than the assumed average?

Or are these fluctuations minor compared to the totals?

Not sure why but I would guess that such bursts might have larger affect when recent that if long ago.

Yes. More carbon-14 in the atmosphere means more CO2 with carbon-14, that means that plants and anything that eats them absorb more carbon-14 and therefore have a higher level 14C and "look" younger.

The generally accepted error is ±50 years, with the known date corrections.

There are local variations and species to species variation (grasses absorb 14C at a different rate than broad leaves, for example)

I would also guess that the older the sample the larger the error, but don't know if a recent burst would have a larger effect.

I decided to do some research on Charlemagne and volcanoes, and the history of the period.

732 Arab defeat at Tours by Charles Martel
742 Charlemagne born in Aachen
753 Pepin the Short, his father, defeats Lombards bothering the pope.
754 Pepin the Short crowned by the pope
768 Pepin dies leaving Charlemagne and brother Carlman in charge
At some point Carlman died and Charlemagne engaged in various conquests
774 our target year — Charlemagne responds to the Pope who is under attack by neighbors. He is subsequently crowned by pope and becomes Holy Roman Emperor
814 Charlemagne dies

Then I looked at volcanoes to see if their was any influence there. Source - Encyclopedia of Volcanoes, Editor Haraldur Sigurdsson. These were listed for Japan as no other data goes back that far except in Europe which had no major volcanic events then. Some time ago I had read that there were over 30 famines in the 100 years following the death of Charlemagne which explained why the Carolingian renaissance faded away. Some of these famines lasted several years.
There were only 3 significant volcanoes (VEI-4 or more) for the period around the 774 event except ones in 751, 764, and 800. For the period during the 100 years after the death of Charlemagne in 814, we have 838, 874, 885, 886, 887, and 915, clearly a busier 100 years.

I would conclude that the 774 event was not caused by volcanoes, but the 100 year famine might have been influence to some extent. Another cause was wheat and rye spoilage cased by introduction of the barberry bush, and it’s rust, used in Arab cuisine, and wheat rust. Colder weather caused by increased volcanic cooling could have interected with these crop pests.
