Short summary
Long-term analysis of 16 solar eclipses over south-central Chile using historical ionograms (1958–2024). Layer-dependent ionospheric responses were quantified, and fragile analog records were rescued and digitized, providing unique insights into eclipse-induced ionospheric variability.
