Study of Interplanetary and Geomagnetic Response of Filament Associated CMEs

TL;DR

This study investigates how filament-associated CMEs influence Earth's geomagnetic activity and examines the challenges in identifying filament material within interplanetary CMEs at 1AU.

Contribution

It provides insights into the interplanetary and geomagnetic responses of filament-associated CMEs and discusses the difficulties in detecting filament material at 1AU.

Findings

Filament material presence correlates with geomagnetic activity levels.

Identification of filament material at 1AU is challenging in complex CMEs.

Filament-associated CMEs can cause moderate to major geomagnetic disturbances.

Abstract

It has been established that Coronal Mass Ejections (CMEs) may have significant impact on terrestrial magnetic field and lead to space weather events. In the present study, we selected several CMEs which are associated with filament eruptions on the Sun. We attempt to identify the presence of filament material within ICME at 1AU. We discuss how different ICMEs associated with filaments lead to moderate or major geomagnetic activity on their arrival at the Earth. Our study also highlights the difficulties in identifying the filament material at 1AU within isolated and in interacting CMEs.
