In the abstract:

>We have located the observational site around Hàojīng (N34°14′, E108°46′) and dated the event to 977 ± 1 or 957 ± 1 BCE. On this basis, we have computed the equatorward extension of the auroral visibility as ≤39.0° in magnetic latitude and reconstructed the equatorward boundary of the auroral oval as ≤45.5° in invariant latitude.

He also goes to Hong Kong to get suits made, he's there when he sees Bart doing a delivery of human eyes (from memory).

And thank you, I'd forgotten we'd parked under the Sunsphere.

Aurorae as far south as China. I wish I could see one for myself.

China can get pretty far North.

I just looked it up, the northernmost point in China that I could find is at roughly the same latitude as Edmonton, Alberta, Canada.

Aurora ovals are centered around geomagnetic poles and not geographic poles. The northern one is tilted heavily towards North America so the chance to see auroras at 53° N China is the same as in Indianapolis (39.7° N)

Was it so heavily tilted towards North America in 900 BC?

HiiohoiHalojata t1_j2ju2wb wrote

That's a great point. Although the north magnetic pole has wandered quite a lot during the past 100 years, the geomagnetic pole has stayed relatively still. However, 3000 years is still a long time so it's definitely possible it was way closer to the geographic poles.

I didn't find any information about its location before 1900. The magnetic pole (not geomagnetic pole) was actually even more tilted towards North America at around 1600 than now

Ancient China (that is, pre-Imperial China), not so much. China had yet to expand far beyond the "Central Plain" at this point in time (early Zhou dynasty, aka Western Zhou period).

Not in the 10th century BC it didn't. Back then, modern Beijing/Hebei was just about the northern limit of Chinese civilization.

The best most of us can aspire to see in our locales is the areola borialis. I've seen their stunning beauty many times, although they do tend to be the most enjoyable during the non moody season.

Excerpt:

>The Bamboo Annals is a chronicle of ancient China, written on bamboo strips, that begins with the age of the Yellow Emperor and runs through the so-called Warring States period (5th century–221 BCE), when rival states were engaged in intense competition. It ended when the state of Qin unified the states.

>The original text of the Bamboo Annals was buried with King Xiang of Wei, who died in 296 BCE, and wasn't discovered until 281 CE, thus surviving Emperor Qin Shi Huang's burning of the books in 212 BCE (not to mention burying hundreds of Confucian scholars alive).

>Independent researcher Marinus Anthony van der Sluijs and Hisashi Hayakawa of Nagoya University relied on the ancient text [version] for their new analysis.

>This text describes the appearance of a "five-colored light" visible in the northern part of the night sky towards the end of the reign of King Zhao of the Zhou dynasty.

>While this is technically an unconfirmed candidate aurora, "The explicit mention of nighttime observation rules out daytime manifestations of atmospheric optics, which sometimes mimic candidate events," the authors wrote.

>Furthermore, "The occurrence of a multicolored phenomenon in the northern sky during the nighttime is consistent with visual auroral displays in mid-latitude regions."

> 

>The authors peg the likely date of the event to either 977 or 957 BCE. The next earliest description of a candidate aurora is found on Assyrian cuneiform tablets dated between 679-655 BCE, three centuries later.

>There are two versions of the Bamboo Annals still in existence. One is known as the "current text," consisting of two scrolls printed in the late 16th century. Many scholars believe this text is a forgery, given the many discrepancies between its text and portions of the original quoted in older books, although some scholars have argued that some parts might be faithful to the original text.

>The other version is known as the "ancient text," and was pieced together by studying the aforementioned quoted portions found in older books, especially two dating back to the early 8th century CE.

I'm curious as to how they got the name. I frequently watch the Aurora Australis and you can't really see the colour (maybe a faint green glow) the other colours like pink and purple are only visible through a camera.

Cro-Magnon cave paintings are believed to be the first known display of auroras and are about 30,000 years old.

Is there a peer-reviewed paper documenting the quote by Fu Pao? The THEMIS webpage was last updated in 2006, and I couldn’t find a primary source that the unnamed author may have cited.

There wasn't really light pollution as we have today, and if the sun is active enough, you can see auroras as far south as Spain in Europe too.

Before common era huh? And what defined the beginning of the common era?

MeatballDom t1_j2kc8uc wrote

The common era is the dating system we use now, we're in the year 2023 of the Common Era (CE). Before the year 1 CE there was the year 1 BCE (Before Common Era), and we count backwards from there.

It's the exact same system used with BC (Before Christ) and AD (Anno Domini). It's the year AD 2023, and the year 2023 CE.

Julius Caesar died in 44 BCE, and 44 BC.

Make sense now?

Oh boy are you wrong. Even the at a distance you can see the green tint, be Lucky enough to stand directly bellow it and it's the most intense light show I've ever seen.

I've seen a green tinge amongst the white (but we can't see it as well as people near the north or south poles). Even with photography though I haven't seen 5 colours so I'm quite curious as to how strong it was!
