Voyager 1 Hourly Magnetic Field and Plasma Data in RTN Coordinates

Hourly resolution merged magnetic field vectors and plasma flow direction angles from the Voyager 1 spacecraft. Data is provided in RTN coordinates, with spacecraft position in Heliographic inertial coordinates, created at NSSDC for COHOWeb. The dataset originates from NASA and was last updated on March 13, 2026.

Use Cases

• Modeling solar wind interactions based on magnetic field vectors.
• Analyzing plasma flow dynamics based on direction angles.
• Correlating spacecraft position with magnetic field measurements.
• Studying long-term trends in interplanetary magnetic fields.

Strengths

• Hourly temporal resolution provides fine-grained time-series data.
• Merged magnetic field and plasma data from a single authoritative source (NASA).
• Coordinates are explicitly defined (RTN and HGI).

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.
