SOHO LASCO C3 Level 0.5 FITS Data: Solar Corona Images

SOHO LASCO C3 Level 0.5 FITS Data provides raw images of the solar corona captured by the Large Angle Spectroscopic Coronagraph's outer instrument. The LASCO C3 coronagraph images the corona from 3 to 30 solar radii with a spatial resolution of 112 arcsec, using a 1024 x 1024 pixel CCD. This dataset is produced by the National Aeronautics and Space Administration.

Use Cases

• Analyze solar corona morphology and structure based on coronagraph imagery
• Study solar activity and coronal mass ejections based on wide-field imaging from 3 to 30 solar radii
• Perform image processing and compression analysis based on the seven techniques mentioned in the description
• Schedule and simulate observation programs based on the described control and scheduling capabilities

Strengths

• Images cover a wide field of view from 3 to 30 solar radii
• Uses a 1024 x 1024 pixel CCD for each coronagraph
• Spatial resolution for C3 is specified as 112 arcsec

Limitations

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