Description

Solicited talk originating from parallel session SWR1.
We present a comprehensive catalogue of solar energetic electron (SEE) events, derived from joint observations by remote-sensing and in-situ instruments aboard the Solar Orbiter spacecraft. The Energetic Particle Detector (EPD) is used to characterise the properties of energetic electrons in situ and to estimate their injection times at the Sun. The timing, location, and intensity of associated X-ray flares is obtained using the Spectrometer/Telescope for Imaging X-rays (STIX), while the Extreme Ultraviolet Imager (EUI) provides complementary observations of the flare evolution and eruptive phenomena. The Solar Orbiter coronagraph (Metis) and heliospheric imager (SoloHI) are employed to characterise potentially associated coronal mass ejections (CMEs). Type III radio bursts detected by the Radio and Plasma Waves (RPW) instrument are used to connect the eruptive solar events to the SEE events observed in situ. We present the catalogue's contents, and the methodology employed to determine key parameters. Finally, we discuss statistical results from the first release of this catalogue.
