Optical observations of solar disturbances causing type II radio bursts

Extract
During 1956-57, 15 type II radio bursts have been recorded on the Dapto radio spectrograph during times of observation with the Sydney Hα flare patrol camera. We believe that we have established identifications of the optical disturbances responsible for 13 of these bursts, and alternative identifications for the remaining two. As Table I shows, some of these were prominences ejected at the limb. Some were disappearing filaments that ejected matter and were accompanied by the development of two parallel lines of flares, one on either side of the position of the former filament. Others were flares, almost all being particularly bright and showing some evidence of dark-hydrogen activity.
