An Analysis of Surges Triggered by a Small Flare
Abstract
On 22 October 1980, near the solar central meridian, in the western vicinity of the large spot group, a subflare of the two-ribbon type was observed. Three surges were associated with this flare. Their starting points were situated close to the principal flare patches on both sides of a short filament that was visible for only a few hours. True flow velocities and decelerations along the arch-shaped surge trajectories have been determined for two of the surges. The event was studied from a series of Ha on- and off-band filter-grams taken through the Debrecen coronagraph of 53 cm aperture.
