Osaka Univ: Confirming the record of the oldest aurora: Iraq, 660 BC
Osaka University / University of KYOTO
Around 660 BC, a description was found indicating that the northern lights appeared around Iraq now.
A group such as Osaka University confirmed that “It is written on the clay plate made at that time”.
It is attracting attention as the world’s oldest aurora record (dating about 100 years ago).
“Assyrian Astrology Report”: Decoding
Groups such as Osaka University and University of Tsukuba tried to decipher the Assyrian Astrology Report compiled by astronomers at that time in Assyria (now Iraq) in the 7th century BC.
As a result, the description of “red light”, “red clouds”, and “red covers the sky” was confirmed on the clay board (which seems to have been made between 680 and 650 BC).
In general, aurora is known to glow blue or green.
However, aurora glowing red may be seen at low latitudes.
