CoSEE-Cat: the Comprehensive Solar Energetic Electron Event Catalogue — •Alexander Warmuth, Frederic Schuller, Song Tan, and Jake Mitchell — Leibniz-Institut für Astrophysik Potsdam (AIP)

We present a comprehensive catalogue of solar energetic electron (SEE) events derived from joint observations of remote-sensing and in-situ instruments on Solar Orbiter. The Energetic Particle Detector (EPD) is used to characterize the properties of energetic electrons in-situ and obtain injection times at the Sun. Timing, position, and magnitude of corresponding X-ray flares are identified with the Spectrometer/Telescope for Imaging X-rays (STIX), which is complemented by the Extreme Ultraviolet Imager (EUI) which provides additional context on the flare evolution and eruptive phenomena. The Metis coronagraph and the SoloHI heliospheric imager characterize the associated coronal mass ejection. Finally, type III radio bursts detected by the Radio and Plasma Waves (RPW) instrument are used to link the eruptive solar events to the SEE events detected in-situ. We discuss the contents of the catalogue, how the various parameters were determined, and discuss statistical results on SEE events obtained from the catalogue.
