Independent Cross-Observatory Analysis of the 3I/ATLAS Perihelion Event (Oct 29–31, 2025)

This dataset and accompanying memorandum document an independent comparative analysis of the 3I/ATLAS perihelion event observed between October 29–31, 2025. The study integrates thermal, spectral, and geomagnetic correlations to evaluate whether synchronized energy signatures detected across multiple observatories correspond to natural solar-geomagnetic coupling or anomalous field perturbations. The report includes timestamped observational data requests, preliminary spectral ratio assessments (Ni/Hg), and a cross-validation framework designed to align international datasets from ESA, NASA, JAXA, ESO, NOIRLab, BGS, and NOAA. The work is intended for open peer collaboration and further verification through transparent data exchange.
