Hα flare of 14 March, 1984 - evidence for reconnection?

Kodaikanal Hα monochromatic and white-light observations are used to study the circular flare of 14 March, 1984. We report here the dynamic activity of the Hα filament, which attained a severe twist before erupting as a 4B flare. We feel that the relative motion between the emerging spot field and its neighbouring field is responsible for the field line reconnection, which triggered the flare.
