Description
Terrestrial cosmogenic isotope records indicate that extreme solar particle events (ESPEs) occurred in the past, with magnitudes exceeding those observed during the space era by orders of magnitude. These rare events occur, on average, approximately once every 1,500 years.
This talk will provide an overview of recent progress in ESPE research, including improved reconstructions from cosmogenic isotopes, advances in atmospheric modeling, and new constraints on the frequency and intensity of such events.
