A celestial event described in an ancient Chinese text is the earliest known to be associated with the candidate aurora, rather than the oldest dating back about three centuries, according to a new study. and Marinus Anthony van der Sluijs, an independent researcher based in Canada. , and Hisashi Hayakawa from Nagoya University. This information was published in a journal Advances in aerospace research.
The Bamboo Annals, or Zhushu Jinian in Mandarin, chronicles the history of China from ancient times to the time of their composition, in the 4th century BC. Aside from historical events, common information in the sky is sometimes found in the text. Although this story has been known to scholars for a long time, a revision of the ancient texts will provide new insights.
In this case, the authors look at the mention of a “five red light” seen in the northern sky at night in the wake of the death of Emperor Zhou. Although the exact year is not clear, they used modern developments of the Chinese period to live in 977 and 957 BC as being about two years, depending on the nature of Zhao’s reign.
They knew the story of the “five -color light” corresponding to a major geomagnetic disaster. When the medium aurora shines, it can show a pattern of many colors. Researchers provide some examples of this from historical accounts closest to our time. The Earth’s northern magnetic field was observed on the Eurasian side in the mid -10th century BCE, at about 15 ° near central China before this time. Therefore, the auroral oval can be seen by observers in central China during times of severe magnetic turbulence. The study assumes that the equatorward boundary of the auroral oval is located at a magnetic latitude of 40 ° or less at that time.
This is the first historical account of an aurora seen from all over the world. The discovery came two years after the holder of this position – records of the candidate auroras were written on cuneiform plates by Assyrian astronomers in the period 679–655 BCE. Some scientists have also linked Ezekiel’s vision, now written in 594 or 593 BC, with auroral vision in the Middle East, but the caveat should be noted for its reliability. Alternatively, another account of the first candidate aurora for 567 BCE appears in the astronomical history of Babylonian King Nebuchadnezzar II.
Why did it take so long for scientists to see the aurora in the five -color light of this writer? One reason is the solid history of the Bamboo Annals. The original document was lost, rediscovered in the 3rd century CE and lost again during the reign of King Song. In the 16th century, a different text was printed on an object in the sky that was not a five -color lamp, but a comet. Now new research shows that this can’t be read before.
It is interesting in itself that the famous descriptions of the northern lights can be released this far in time. Historical knowledge is valuable for other reasons, however. It helps scientists model long -term patterns of differences in the atmosphere and the function of the sun, over time from years to millennia. Understanding these changes can help companies prepare for future eruptions and eliminate the need for more technology. This story is the only historical account of a catastrophic event before the Homeric Grand (Solar) Minimum (810–740 BCE), better known as the Neo-Assyrian Grand Minimum for debate of the history and days of Homer.
