Collision trace
The magnetosphere rests in gentle equilibrium today — K-index at 2.33, barely a whisper above baseline. Proton flux measured 0.35 pfu, setting freq1 to a modest 1.4 Hz, while the solar wind's 441 km/s velocity lifts freq3 into active territory at 2.2 Hz. A five-fold symmetry captures this threshold moment: quiet, but listening.
