Collision trace
The magnetosphere registers a K-index of 3.67 today — moderate structure beginning to crystallize. Proton flux at 0.45 pfu keeps the fundamental frequency gentle at 1.45 Hz, while the solar wind's 426 km/s velocity adds a subtle tremor at 2.20 Hz. Six-fold symmetry emerges from the geomagnetic threshold, a hexagonal mandala for a quiet storm.
