Description
The satellite PROBA-V with the Energetic Particle Telescope (EPT) onboard, was launched on 7 May 2013 onto a polar Low Earth Orbit of 820 km altitude. Almost continuously in operation, EPT has provided flux spectra data for electrons (0.5–8 MeV), protons (9.5–248 MeV) and α-particles (38–980 MeV) with a time resolution of 2 seconds. Hence, the EPT data set covers already one full solar cycle period and continues its measurements for already one more year, thus starts for spanning the time series over one more solar cycle. EPT did witness the Saint-Patrick storm (March 2015) and the exceptional September 2017 solar energetic particle event of the falling phase of solar cycle 24, as well as the minimum activity around 2020 when outer belt electrons did nearly vanish, but also their great coming back in May 2024. The presentation will give an overview of the most remarkable measurements of the instrument till today, as well as features and caveats of the dataset
