First up, from Gizmodo, October 16, 2019:
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....

That meander down memory lane was triggered by a recent report of an even earlier event.
From SpaceWeather, May 24:
Trees Remember an Ice Age Solar Storm
More than 14 thousand years ago, there was a solar storm so big, trees still remember it. Dwarfing modern solar storms, the event would devastate technology if it happened again today. Spoiler alert: It could.
The record-strong storm is described by a paper in the upcoming July 2025 edition of the peer-reviewed journal Earth and Planetary Science Letters. It occured in 12,350 BC and is classified as a “Miyake Event.”
Miyake Events are solar storms that make the Carrington Event of 1859 look puny. Trees “remember” them in their rings, which store the carbon-14 created by gargantuan storms. At least six Miyake Events have been discovered and confirmed since Fusa Miyake found the first one in 2012. The list so far includes 664-663 BC, 774 AD, 993 AD, 5259 BC, 7176 BC, and 12,350 BC.
The Miyake Event of 12,350 BC is especially intriguing. It appears as a carbon-14 spike in Scots Pine trees along the banks of the Drouzet river in France, with a matching beryllium-10 spike in Greenland ice cores. The event was global and, based on the size of the spikes, very big....

And even earlier (one of the tablets cleaned up real nice, and translated):
