Resumen:
We present spectral observations of the continuum as well as the profiles of 29 selected atomic lines for the two continuum-emitting kernels of the 1982 June 15 white-light flare, and for the neighboring quiet Sun. We find that one of the kernels does not show enhanced emission in chromospheric lines, particularly in Hα, although it presents the same level of white-light emission as the other kernel. This suggests that both kernels have the same thermal structure in the continuum-emitting region, but a different structure in the chromosphere, thus supporting the hypothesis that the continuum emission is of photospheric origin, and due to H - .
