Vega 1 Magnetic Field Data During Halley Comet Flyby

Vega 1 spacecraft's 1-minute magnetic field measurements during its closest approach to Halley's Comet. Data is presented in the spacecraft-centered solar ecliptic (SE) coordinate system, with Bxse, Byse, and Bzse components. This dataset was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Modeling the comet-solar wind interaction based on the magnetic field vector data.
• Analyzing temporal changes in the magnetic environment based on the 1-minute resolution time series.
• Correlating spacecraft position with magnetic field perturbations based on the provided cometocentric (CSE) coordinates.

Strengths

• Data is from a specific, historic mission event: the Vega 1 spacecraft's closest approach to Halley's Comet.
• Magnetic field vectors are provided in a defined spacecraft-centered solar ecliptic (SE) coordinate system.
• Spacecraft positions are provided in a separate cometocentric solar ecliptic (CSE) coordinate system.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
