TL;DR
This study reports a complex solar event involving two filament eruptions and a coronal jet, highlighting the intricate interactions and diverse phenomena in solar activity observed with multiple instruments.
Contribution
It presents detailed multi-instrument observations of a sympathetic filament eruption and associated jet, revealing new insights into filament interactions and jet propagation paths.
Findings
First filament eruption triggered a second, sympathetic eruption.
The second filament's eruption was a failed one with fallback of material.
A large coronal jet was produced, showing deflected trajectory without clear magnetic reconnection evidence.
Abstract
Combining the high-quality observations from the {\it Solar Dynamics Observatory} (SDO), the Global Oscillation Network Group (GONG), and the Chinese H Solar Explorer (CHASE), we report a solar coronal jet triggered by the sympathetic eruption of two filaments on 2024 January 11. Initially, the western segment of an active region filament erupted. The erupting plasma propagated eastward, approximately along the filament's axis. This eruption perturbed the magnetic field of a second filament situated near its eastern footpoint, the second filament then erupted sympathetically about one hour later. The eruption of the second filament is a failed one, with the majority of the filament material falling back after the initial lifting. Although no GOES flare accompanied these filament eruptions, distinct brightenings were observed following each eruption. The second eruption produced…
