Fig. 3.From: Effect of SC on frequency content of geomagnetic data using DWT application: SC automatic detectionEnlarged window of the H-component around the SC and the period in which the rate of variation is calculated. In the left subfigure, we can notice that there is no discontinuity in the trace. In the right subfigure, a discontinuity in the trace can be recognized. The rate is calculated in the period between the vertical lines drawn in each subfigure.Back to article page
