Magnetic keogram showing the dynamics of latitudinal distribution of magnetic variability magnitude |dX/dt| along the IMAGE profile during the storm main phase 04–24 UT. Color coding is saturated to reveal signatures of weaker magnetic field variability. Codes and geomagnetic latitudes of selected IMAGE stations are indicated near the right-hand Y-axis. Arrows mark substorm #1–6 activations
