Left: He intensity map obtained by integrating Ic − I over the wavelength covered by the He absorption (10 828–10 835.7 Å). The intensity contribution of the photospheric and telluric spectral lines in the chosen wavelength range has been subtracted. Right: Hα image obtained with the slit-jaw camera at the VTT at 14:22:33 UT. The contour line indicates the position of the inversion line of the magnetic field in the photosphere, that is, where γ = 90° (see Fig. 2).
