The white-light flare of 1982 June 15: A midchromospheric kernel

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 si...
