摘要: We study a flare which occurred on 3 November 1997 at 10:31 UT in the vicinity of parasitic polarity AR 8100. Using SOHO/EIT 195 A observations, we identify brightening thin transequatorial loops connecting 8100 and 8102, dimmings located between two active regions. Difference images highlight presence loop-like structure rooted near location usually called an EIT wave. The corona] magnetic field derived from potential extrapolations SOHO/MDI magnetogram shows that topology is complex polarity. There, ‘bald patch’ (defined as locations where tangent to photosphere) present. conclude was patch flare’. Moreover, extrapolation confirms there large coronal volume filled with lines interconnecting overlaying bald patch.
