ANO-003: RFS-X Research Dataset, March–April 2026

This dataset contains the operational output of the RFS-X heliospheric field state monitoring system (Resonance Coherent Systems) for the period March 1 – April 30, 2026. It covers the ANO-003 event window — the first recorded CPS maximum (score 100) in system history and a documented 27-hour precursor detection preceding an X1.5 solar flare. The dataset is released to support independent review of the RFS-X validation record described in the companion Methodology Note (DOI: 10.5281/zenodo.20518466).
