Overview

• An Astronomy & Astrophysics paper published today presents a Comprehensive Solar Energetic Electron event Catalogue (CoSEE-Cat) for public use.
• Researchers identified more than 300 events recorded from November 2020 to December 2022 using eight Solar Orbiter instruments.
• In-situ data from the Energetic Particle Detector were paired with simultaneous remote sensing to tie electron streams to specific solar eruptions.
• The study distinguishes impulsive, flare-driven bursts from gradual, CME-driven swells, with CME-related events carrying higher operational risk.
• Apparent detection lags arise partly from turbulence and scattering in the solar wind, and the results will inform ESA’s Vigil mission in 2031 and the upcoming Smile mission.
