The authors present spectroscopic data for three flares obtained with the Bent Crystal Spectrometer flown in the Solar Maximum Mission in 1980. This data is concerned with the structure of the Ca XIX resonance line at 3.176 Å during the impulsive phase of flares. On the basis of high time resolution (6s.) data, the authors suggest that the previous published results concerned with the excess broadening of the resonance line being due to bulk random mass motions may give an over-simplified picture. Instead the authors suggest that during this stage of the flare, the resonance line consists of many discrete features, which are interpreted as mass flows.
