✦ Synopsis

A number of studies of the 1-10 A emission during solar flares have been reported in the last several years. Results of data from proportional counters (Kahler et al., 1970;Culhane and Phillips, 1970), GM tubes (Drake, 1970), ion chambers (Horan, 1970), and crystal spectrometers (Meekins et aL, 1970;Neupert, 1968) have generally been consistent with a thermal emission interpretation. The reported temperatures cover a range of ~4 x 106 < T<40 x 106 K. In contrast to these results, Elwert and Haug (1970) have interpreted proportional counter data from two solar X-ray flares as due to nonthermal bremsstrahlung. We wish to discuss several objections we have to their interpretation.
