    The OP got the dates wrong.
    Here is the info from the article:

    "Evidence of an enormous solar storm that struck the Earth around 2,610 years ago has been found in ice cores from Greenland.
    These phenomena, called solar proton events (SPEs), represent a threat to modern society in terms of communication and navigation systems, space technologies, and commercial aircraft operations.
    Evidence of such events is recorded in annually resolved natural archives, such as tree rings and ice cores (drilled samples of ice).
    To learn more about SPEs, Lund University’s Professor Raimund Muschelerand his colleagues from Sweden, France, Switzerland, Korea, the UAE, and the US analyzed ice cores from Greenland.
    The material contained evidence of a very powerful solar storm that occurred in 591 BC.
    It is only the third such event reliably documented and is comparable with the strongest SPE detected at 775 CE.
    “We also took part in research that confirmed the existence of two other massive solar storms, using both ice cores and the annual growth rings of old trees,” Professor Muscheler explained.
    “Those storms took place in 775 CE and 994 CE.”
    The findings were published online this week in the Proceedings of the National Academy of Sciences."

    Great Info again Bonnie I remember a large CME years ago back when Art Bell was on 80# meters & the band went dead ! the next morning I read that 3 satellites DIED ! big communication "BIRDS" as we at AMSAT say ! By the way the "Alpha Hotels" keep showing up ! Hi Hi 73' Phil KI6PMD..

    So if I got the dates correct, roughly speaking 1500 years between the first two events, 200 between the second and third, and then 800 until the Carrington event. Not much of a pattern (not much data though).

    Them protons are killahs!

    Here's hopin' we don't see a major proton event in our lifetime.

    Dang , I wanted to conner the market on protons , with my new home brew proton collector ;)
    The I could trade propagation other goodies

    True, though according to https://www.space.com/7224-150-years-worst-solar-storm.html the Carrington was three times as bad as 1989. And I wonder about all the unshielded electronics in cars, aircraft, PCs, hospitals, factories, etc. I've read science fiction stories where aliens (or a major foreign power) used a super electromagnetic pulse to fry the world's "nervous system."
