STEREO-A IMPACT/MAG: Magnetic Field Vectors in RTN Coordinates, 2015 Solar Conjunction

STEREO Ahead spacecraft reprocessed magnetic field vector data from the IMPACT/MAG instrument, expressed in Heliographic Radial-Tangential-Normal coordinates. The dataset includes six versions of processing, with corrections for offsets, sensor glitches, and timing issues applied incrementally. It was produced by NASA and last updated on the platform in March 2026.

Use Cases

• Modeling solar wind propagation based on magnetic field vector components.
• Analyzing coronal mass ejection (CME) transients based on the described magnetic field data.
• Developing sensor correction algorithms based on the documented glitch and timing issue resolutions.
• Studying heliospheric magnetic structure during the 2015 solar conjunction period.

Strengths

• Includes six documented versions of data processing, showing iterative improvements.
• Specific corrections applied are detailed, including offset, glitch, and timing fixes.
• Data originates from the NASA STEREO mission, a recognized scientific source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file formats, and sample data are unknown, limiting suitability assessment.
