Semi-automated Method for Failed Eruptions Search in SDO Data Base: Methodology and First Results
Abstract
It is well known that not all solar flares are connected with eruptions followed by coronal mass ejection (CME). Even strongest X-class flares may not be accompanied by eruptions or are accompanied by failed eruptions. There are several mechanisms responsible which were proposed. Present observations of SDO/AIA give a chance for deep statistical analysis of properties of an active region that may confine an eruption. Therefore, we developed automated method
which can recognize moving structures and confined eruptions in AIA images. We present the algorithm and its performance for 1 April 2012 - 1 July 2012 period. The algorithm found more than 600 dynamic events. More than 30% of them are failed eruptions. Developed algorithm is very effective and gives a chance for huge increase of failed eruption data base.- Publication:
