Abstract:
This study focuses on describing the dynamic events present in the low corona as observed by PROBA2/SWAP instrument, in the period May-August 2010. Among these phenomena we mention: dimmings, brightenings, waves, flares, post-eruptive arcades, filament activations, filament/prominence eruptions, UV jets, etc.Statistic distribution of events shows a peculiar asymmetry which is thoroughly discussed. Analisys of complimentary data pointed out that the asymmetry could be a real phenomena of solar activity.
