Study of the Flare?Surge Event of September 7, 1958

Abstract

Giovanelli and McCabe (1958) indicate that, while most flare-surges appear dark against the solar disk throughout the greater part of their existence, it is not uncommon for a surge in its earliest stages, just as it leaves the flare, to be bright. Rapidly moving material that remains bright against the solar disk for a longer time is much less frequently observed. Of the cases of longer lasting bright surges that have been reported as exceptional events by Dodson and Hedeman (1949, 1952), Ellison (1950), Dodson and McMath (1952), Bray, Loughhead, Burgess, and McCabe (1957), and Reid (1959), those reported by Dodson and McMath, by Bray et al., and by Reid appear to be detached and rapidly moving portions of flares, whereas the remainder did not attain flare brightness.
