Sympathetic Quiet and Active Region Filament Eruptions

TL;DR

This paper analyzes three interconnected filament eruptions on the Sun, revealing how one eruption can trigger others and lead to a coronal mass ejection and solar flare, using multi-wavelength solar observations.

Contribution

It presents detailed observations of sympathetic filament eruptions and their causal relationships, highlighting the dynamics leading to solar eruptions and associated space weather events.

Findings

Eruption of F1 triggered F2 and F3 eruptions.

F2 and F3 merged and caused a CME and flare.

Filament eruptions are interconnected and can trigger space weather phenomena.

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/EUV wavelengths by Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory and by Global Oscillation Network Group telescope in H{\alpha} line. As filament F1 starts to erupt, a part of it falls close to the location of the F2 and F3 filaments. This causes the eruption of F2 and F3 during which the two filaments merge together and trigger a medium-class CME and a long-duration GOES C2.1 class flare. We discuss the dynamics and kinematics of these three filament eruptions and related phenomena.
