Scientists report that they may have found the
earliest written record of a solar storm in ancient Assyrian tablets. Recent analyses have found evidence of an extreme solar storm that left energetic particles in
tree rings and
ice cores across the world sometime around 660 BCE.
With this in mind, a research team in Japan and the United Kingdom wondered if they'd be able to find evidence of this storm in ancient astrological records — and they may have found something in Assyrian tablets.
Back in the 19th century, archaeologists uncovered thousands of tablets dating back to the Assyrian empire in Mesopotamia, which documented treaties, stories, including the now-famous epic of Gilgamesh, and astrological reports. These reports included observations of the planets, phenomena like comets and meteorites, and of course, predictions of omens.
The researchers (today's researchers) scanned through a collection of these
astrological reports in search of auroral-type events, which they define as "reddish luminous phenomena in the sky" and are caused by the Sun's particles interacting with the atmosphere. Many of the reports weren't dated, but the researchers could at least produce date ranges based on the astrologer who wrote the report.
They found three reports that seemed to mention auroral phenomena: one reporting a "red glow," another a "red cloud," and a third reporting that "red cover[ed] the sky," according to
the paper published in
The Astrophysical Journal Letters.
