Solar Orbiter SoloHI: Decompressed Uncalibrated Heliospheric Images

SoloHI Level 1 data provides decompressed, uncalibrated image data from the Solar Orbiter Heliospheric Imager. The images are rectified so the right side corresponds to the spacecraft's sunward (+X) direction, with data units expressed in DN. The dataset is maintained by the National Aeronautics and Space Administration and was last updated on March 13, 2026.

Use Cases

• Analyze raw heliospheric intensity patterns based on DN (Data Number) units
• Study spacecraft orientation relative to solar features based on the rectified sunward (+X) direction
• Process and calibrate raw space imagery for downstream scientific analysis

Strengths

• Data originates from a NASA mission, suggesting authoritative source instrumentation.
• Images are rectified to spacecraft orientation, providing a consistent spatial reference.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
