Real 3-hourly geomagnetic ap index 1932-present --- solar-driven magnetic storms, 93 years (CC BY 4.0, GFZ)
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 Predictability:transition_entropy_variance (+3.3z) — beyond what the standard bank predicts for it.
Predictability:transition_entropy_variance | +3.4z | bank-miss 1.3σ |
Level Statistics:wd_classification | -2.1z | bank-miss 1.5σ |
