Sympathetic Quiet and Active Region Filament Eruptions
Abstract
We present the observations of three sympathetic filament eruptions occurring on 19 July 2015, namely F1, F2, and F3. The events were observed in UV and EUV by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory and by Global Oscillation Network Group telescope in Hα line. As filament F1 starts to erupt, a part of it falls close to the locations of filaments F2 and F3. Our observations indicate that this drives the eruption of F2 and F3, which merge in the process, and trigger a coronal mass ejection and a long-duration GOES C2.1 class flare. We discuss the dynamics and kinematics of these three filament eruptions and related phenomena.
