STEREO-A PLASTIC: Suprathermal Proton Event List

NASA's STEREO-A spacecraft provides a list of automatically identified suprathermal proton events measured by the PLASTIC instrument's Wide Angle Partition without a Solid State Detector (WAP non-SSD). The data product is intended for use in conjunction with magnetic field and solar wind data to identify energetic proton events related to Stream Interaction Regions, shocks, and magnetospheric events. The dataset was last updated on March 13, 2026.

Use Cases

• Identify Stream Interaction Region (SIR) events based on suprathermal proton measurements.
• Analyze shock-related energetic proton events based on the automatically identified event list.
• Study upstream events and magnetospheric events using the conjunction of proton, magnetic field, and solar wind data.
• Correlate suprathermal proton activity with solar wind parameters mentioned in the description.

Strengths

• Data originates from the STEREO-A spacecraft, a NASA mission.
• Events are automatically identified, suggesting a standardized detection method.
• Last updated on March 13, 2026, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific instrument's operational period.
