Helios 2 E1: Hourly Solar Wind Plasma Data from the Rosenbauer Detector

Helios 2 E1 (Rosenbauer) Hourly Plasma Data provides averaged solar wind measurements from the Helios 2 spacecraft. The dataset includes time, spacecraft position, proton bulk speed, temperature, density, flow angles, and parameter standard deviations. NASA produced this data, which was last updated on the platform in March 2026.

Use Cases

• Modeling solar wind propagation based on proton bulk speed and flow angles.
• Analyzing solar wind parameter correlations based on temperature, density, and speed.
• Studying spacecraft position effects on measurements based on sun-Helios distance and Carrington longitude.
• Assessing data variability based on the standard deviations of plasma parameters.

Strengths

• Data originates from the authoritative NASA Helios 2 mission.
• Includes derived statistical measures such as standard deviations for key plasma parameters.
• Last platform update recorded as 2026 03 13 07:09:38.509377.

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, which may require specialized tools for access.
