VG2 NEP CRS: Voyager 2 Electron Counting Rates at Neptune

Voyager 2's Cosmic Ray System electron telescope recorded high-resolution electron counting rates during the spacecraft's encounter with Neptune. The D1 detector likely captures electrons with kinetic energies above approximately 1 MeV. The data was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Analyze electron flux variations based on high time resolution counting rates.
• Model cosmic ray interactions near Neptune based on electron energy data.
• Validate detector performance based on the described D1 detector response.

Strengths

• Data originates from the Voyager 2 spacecraft, a primary source for outer solar system science.
• The description specifies a high time resolution for the counting rates.
• The detector's response to electrons above approximately 1 MeV is defined.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
