STEREO-A Carrington Maps: Solar Corona Evolution

Synoptic maps summarize short-term and long-term coronal evolution from the STEREO mission. East and West limb maps from the Cor1 and Cor2 coronagraphs, HI1/2 imagers, and central meridian maps from the EUVI telescope are available for each Carrington Rotation since the mission's start. The maps illustrate the corona's evolution from a simple two-sectored structure to a complex multi-sectored one.

Use Cases

• Analyze coronal mass ejections based on distortions and discontinuities visible in limb maps.
• Study the evolution of the solar corona from a simple to a complex structure based on the map series.
• Correlate active regions on the sun with streamer belt distortions based on the limb map data.
• Investigate long-term changes in the lower solar atmosphere based on EUVI meridian maps.

Strengths

• Maps are available for each Carrington Rotation since the start of the STEREO mission.
• Data includes multiple perspectives from different instruments: Cor1, Cor2, HI1/2, and EUVI.
• The dataset demonstrates the evolution of the corona over time.

Limitations

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