摘要: A recurrent Hα surge was observed on 7 October, 1991 the western solar limb with Meudon MSDP spectrograph. The GOES satellite recorded X-ray subflares coincident all three events. During two of surges high-resolutionYohkoh Soft Telescope (SXT) images have been taken. Low loops overlying active region where occurred were continuously restructuring. flare loop appeared at onset each event and somewhat separated from footpoint surge. are interpreted as causally related to surges. It is suggested that due magnetic reconnection between a twisted cool open field lines. Cold plasma bubbles or jets squeezed among untwisting lines could correspond material. No detection made either emission along path jets, possibly because finite threshold theYohkoh SXT.
