    Very High Energy Solar Energetic Particle Events and Ground Level Enhancement Events: Forecasting and Alerts by N. Crosby, H. Mavromichalaki, O. Malandraki, M. Gerontidou, M. Karavolos, D. Lingri, P. Makrantoni, M. Papailiou, P. Paschalis, A. Tezari

    Published 2024-09-01
    “…From the space‐based approach, the HESPERIA UMASEP‐500 product, jointly developed within the framework of the EU HORIZON2020 HESPERIA project by the Universidad de Malaga, Spain and National Observatory of Athens, Greece, provides forecasts of GLE events and >500 MeV protons relying on GOES satellite Soft X‐Ray and high energy proton observations. These two products are fully integrated as federated products on the ESA SWE Portal and are provided as part of the ESA Space Safety Program Space Weather Service Network. …”
