What It Is

Real 3-hourly geomagnetic ap index 1932-present --- solar-driven magnetic storms, 93 years (CC BY 4.0, GFZ)

Interpretation

Standard analysis sees: heavy-tailed; right-skewed; time-irreversible (sharp rises, slow decay). The atlas finds no named structure, but the source is distinctively extreme on Level Statistics:wd_classification (-2.1z) — beyond what the standard bank predicts for it.
