Problems in relating the optical and X-ray emissions from a solar flare.
Abstract
We evaluate the possibility that the short-lived Balmer line emission at H9 λ3835 Å of the 1972, August 2 (1839 UT) solar flare is due to heating of the chromosphere by bombarding electrons. We point out some of the problems of comparing the time behavior and spatial distribution of simultaneous hard and soft X-ray emissions. It is concluded that the present data do not justify the attribution of the short-lived optical emission to the presumed hard X-ray producing electrons.
