Collision trace
A K-index of 5.67 today — the magnetosphere caught between calm and storm, traced in heptagonal symmetry. Proton flux at 0.37 pfu sets a gentle fundamental at 1.37 Hz, while solar wind at 599 km/s drives the third oscillator to 3.49 Hz, nearly touching the threshold of fast wind resonance.
