The time evolution of external coefficients \(C_{jm}^{\mathrm{(e)}}\) and \(S_{jm}^{\mathrm{(e)}}\) (red), and internal coefficients \(C_{jm}^{\mathrm{(i)}}\) and \(S_{jm}^{\mathrm{(i)}}\) (blue) up to degree \(j=5\) whose magnitudes are larger than 1 nT. Time span covers the magnetic storm analysed in Fig. 1
