STEREO-A IMPACT (In-Situ Measurements of Particles and CME Transients) Solar Electron Proton Telescope (SEPT) 1-min Level 1 Electron and Proton Spectra

Published by NASA Space Physics Data Facility (SPDF) Coordinated Data Analysis Web (CDAWeb) Data Services | National Aeronautics and Space Administration | Metadata Last Checked: September 14, 2025 | Last Modified: 2025-09-10
The IMPACT Solar Electron Proton Telescope (SEPT) Level 1 data consist of electron and proton fluxes from each of 32 energy bands that span ~20 keV to 2000(electrons) or 7000(protons) keV. These spectra are determined each minute, in each of 4 directions with 60 deg fields of view (parallel and anti-parallel to the Parker magnetic field direction, and northward and southward from the ecliptic plane.
