Ulysses COSPIN-HFT: 10-Minute Average Proton and Heavy Ion Fluxes

NASA's Ulysses spacecraft recorded energetic particle fluxes from the Sun and interstellar space. The High Flux Telescope measured spin-averaged and sectored counting rates for protons and heavier nuclei. Data is aggregated into 10-minute average nominal fluxes.

Use Cases

• Modeling solar energetic particle event propagation based on sectored counting rates.
• Analyzing galactic cosmic ray anisotropy based on spin-averaged fluxes.
• Correlating solar wind conditions with heavy ion flux measurements.
• Studying long-term trends in interplanetary particle populations.

Strengths

• Data originates from the NASA Ulysses mission, a primary source for out-of-ecliptic solar observations.
• Provides both spin-averaged and directional (sectored) flux measurements for nuanced analysis.
• Includes fluxes for protons and heavier nuclei, allowing for species-specific studies.

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 a BIN format, requiring specialized tools for access and parsing.
