Collision Trace

K-index at 3.67 marks the threshold where quiet becomes restless — the magnetosphere tensing but not yet yielding. Proton flux barely registers at 0.38 pfu, yielding a fundamental frequency of 1.76 Hz, while solar wind screams past at 629 km/s, driving the tertiary oscillation to 4.12 Hz. The geometry remembers: six arms reaching outward like field lines seeking equilibrium.
