STEREO-A Carrington Maps: Solar Corona Evolution from EUVI Telescope

Synoptic maps from the STEREO mission's SECCHI EUVI telescope illustrate the evolution of the solar corona. The resource contains East and West limb maps from coronagraphs and imagers, plus central meridian maps for each Carrington Rotation since the mission's start. Maps show the corona's transition from a simple two-sectored structure to a complex multi-sectored one, with distortions linked to active regions, the current sheet, and coronal mass ejections.

Use Cases

• Tracking long-term coronal evolution based on Carrington Rotation maps.
• Analyzing associations between streamer belt distortions and solar active regions.
• Studying the shape of the heliospheric current sheet using limb map data.
• Investigating the impact of coronal mass ejections on coronal structure.

Strengths

• Maps are available for each Carrington Rotation since the STEREO mission began, providing a continuous temporal series.
• Data originates from the NASA STEREO mission, a primary source for solar observations.
• Includes multiple map perspectives: limb maps from coronagraphs and imagers, and central meridian maps from EUVI.

Limitations

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