Popis: A study of the energetics and mass transfer during the X-ray flare on Sept. 5, 1973, using the observations in the objective grating mode of the spectrographic telescope on Skylab is presented. The data are approximately monochromatic images of a small X-ray source which show a continued rise in the emission for several minutes followed by a decline. The observations are analyzed using a two-temperature model to determine the changes in the distribution of emission measure and of the amount of material as a function of temperature. The development of the flare can be divided into three periods comprising evaporation which drives mass into the entire emitting region, cessation of evaporation, and decline in the emission measure.
