Impulsive solar flare heating according to UV observations.
Abstract
Previous theoretical calculations of chromospheric heating during solar flares are reviewed for the cases of impulsive heating (characterized by constant density) and long-term heating (characterized by constant pressure). These calculations are compared with data obtained by UV flare observations from the OSO-4 and OSO-6 satellites. It is found that the temperature dependence of the 'average' subflare emission measure at temperatures in excess of 100,000 K is in agreement with the predictions of the impulsive-heating model.
