Resumen:
We study a third kernel of the white-light flare of 1982 June 15, which presents little continuum emission, and it is not particularly bright in Hα. However, it is the brightest kernel as seen in lines formed in the mid-chromosphere. We find that the energy requirements to sustain this kernel are similar to the ones required for the white-light kernels, but the energy is deposited higher. We find that these requirements are compatible with the energy been deposited by an electron beam with an input energy flux of 2 × 108 ergs cm-2 s-1, a low-energy cutoff of 45 keV and a spectral index δ = 6.
