SIDC daily international sunspot number. Strong ~11-year solar cycle on top of intermittent active-region bursts.
Standard analysis sees: multifractal. The atlas finds no named structure, but the source is distinctively extreme on Predictability:entropy_decay_rate (+3.9z) — beyond what the standard bank predicts for it.
Predictability:entropy_decay_rate | +3.9z | bank-miss 2.0σ |
H² × ℝ (Thurston):hyperbolic_variance | +2.1z | bank-miss 1.4σ |
