C-1.4 Class Flare and An Associated Peculiar Coronal Jet

TL;DR

This study analyzes a C-1.4 class solar flare and a peculiar two-stage coronal jet using multi-instrument observations, revealing detailed dynamics of jet eruption and magnetic interactions.

Contribution

It provides new insights into the two-stage eruption process of coronal jets associated with small solar flares.

Findings

The jet erupts in two distinct stages during the flare.

The second stage involves interaction with a nearby magnetic field domain.

The observations reveal the detailed timing and structure of the jet and flare.

Abstract

Using HINODE/XRT, GOES, SDO/AIA observations, we study a compact C-1.4 class flare outside a major sunspot of AR 12178 on 4 October 2014. This flare is associated with a peculiar coronal jet, which is erupted in two stages in the overlying corona above the compact flaring region. At the time of flare maximum, the first stage of the jet eruption occurs above the flare energy release site, and thereafter in the second stage its magneto-plasma system interacts with the overlying distinct magnetic field domain in its vicinity to build further the typical jet plasma column.
