Filament eruption deflection and associated CMEs

TL;DR

This paper reports on a solar filament eruption that exhibited significant non-radial deflection, observed through multiple space-based instruments, and was associated with a weak CME, providing insights into filament dynamics and CME association.

Contribution

It presents detailed multi-instrument observations of a non-radial filament eruption and its associated CMEs, highlighting the deflection behavior and weak CME signature.

Findings

Filament eruption was highly non-radial in nature.

Part of the filament erupted westward, while most deviated eastward.

A weak CME was observed in association with the eruption.

Abstract

We present the observations of a quiescent filament eruption and its deflection from the radial direction. The event occurred in the southern solar hemisphere on 2021 May 9 and was observed by the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO), by the STEREO A Observatory and GONG. Part of the filament erupted in the west direction, while major part of the filament deviated towards east direction. LASCO observed a very weak CME towards the west direction where it faded quickly. Moreover, the eruption was associated with CME observed by STEREO A COR1 and COR2. Our observations provide the evidence that the filament eruption was highly non-radial in nature.
