Abstract
X-ray observations from Vela-5 spacecraft of five flares occurring in November and December 1969 were leduced to temperatures and emission measures as a function of time. This reduction was done assuming a thermal spectrum including free-free and free-bound emission. A phenomenological model is proposed to explain the nature of the time behavior of the temperature and emission measure.
