Studies of Flares and Disappearing Magnetic Flux

摘要

Research accomplishments include: 1) Research on 'flaring arches'; 2) A collaborative paper on 'Anomalously Dense Flare Loops' was published; 3) The footprints of the 'giant arches' previously discovered by Z. Svestka were found in hydrogen alpha observations from the Big Bear Solar Observatory and the Udaipur Solar Observatory, 4) Several sets of new observations showing a relationship between cancelling magnetic fields and flares were acquired and analyzed; 5) A new hypothesis is advanced that cancelling magnetic fields are necessary condition for the energy build-up to solar flares.
