Average of the data from the right panel of Fig. 5 over the latitudinal band −30° ≤λ ≤ −15° in the South. The averages of B_Φ are given by the blue curves (far side), the averages of |B_los| by the black curves (near side), and the average of |B_los| from SO/PHI for 18 November 2020 by the orange curve. The magnetic field data are further smoothed in longitude with a running mean over 4°. The filled areas below the curves highlight the values above 20 G. The red star indicates the same flare (M 4.4), as shown in Fig. 5.
