STEREO-B IMPACT SEPT: 1-Minute Electron and Proton Flux Spectra

One-minute resolution electron and proton flux spectra from the STEREO-B spacecraft's IMPACT Solar Electron Proton Telescope (SEPT). The data consist of fluxes from 32 energy bands spanning ~20 keV to 2000 keV for electrons and 7000 keV for protons, measured in four directions. The dataset is produced by the National Aeronautics and Space Administration.

Use Cases

• Analyze solar energetic particle event timing based on one-minute temporal resolution
• Study electron and proton energy spectra evolution based on 32 distinct energy bands
• Investigate directional anisotropy of particle fluxes based on measurements in four distinct viewing directions
• Model solar particle acceleration mechanisms based on fluxes spanning ~20 keV to 7000 keV

Strengths

• Provides fluxes from 32 distinct energy bands for both electrons and protons
• Offers one-minute temporal resolution for detailed event analysis
• Includes directional measurements from four fields of view (parallel, anti-parallel, northward, southward)
• Energy ranges span ~20 keV to 2000 keV for electrons and 7000 keV for protons

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is stored in BIN format, which may require specialized tools for access
