1/f noise (PSD ~ 1/f) --- equal energy per octave, ubiquitous in nature from heartbeat intervals to semiconductor flicker noise. Between white noise and Brownian motion
Standard analysis sees: no strongly notable standard properties. The atlas finds no named structure, but the source is distinctively extreme on Predictability:entropy_decay_rate (+2.1z) — beyond what the standard bank predicts for it. It sits beside VLF Radio (Baseline) in the atlas (standard-bank rank 23) — a neighbor conventional features miss.
