The record of the oldest aurora is confirmed. Around Iraq around 660 BC, November 17, 15:01
Groups such as Osaka University confirmed that the description of the appearance of the northern lights around Iraq around 660 BC was written on the clay plates made at that time. It is attracting attention as the world's oldest aurora record, dating back about 100 years.
Groups such as Osaka University and University of Tsukuba attempted to decipher the Assyrian Astrology Report compiled by astronomers at that time in Assyria, which is now in Iraq in the 7th century BC.
As a result, it was confirmed that descriptions such as “red light”, “red clouds”, and “red covers the sky” were confirmed on a clay plate that was thought to have been made between 680 and 650 BC.
Aurora is known to shine blue or green, but aurora that shines red may be seen at low latitudes.
Analyzes so far have revealed that a solar storm that disturbed the Earth's magnetic field occurred due to a large-scale solar surface explosion phenomenon "solar flare" around 660 BC. It seems to be aurora.
The oldest aurora record in the world has been dated 567 BC in the Babylon Astronomical Diary, but it dates back about 100 years and is attracting attention.
Naoshi Hayakawa of the Graduate School of Letters, Osaka University, who worked on the study, said, “We were able to support natural science estimates from the literature. We would like to investigate other literature and clarify the astronomical phenomena before BC”. The
