# Quiet Region Jet by Eruption of Minifilament and Associated Change in Magnetic Flux

## TL;DR

This study documents a quiet region solar jet caused by a minifilament eruption, analyzing its formation, eruption, and associated magnetic flux changes, providing insights into the magnetic dynamics leading to jet activity.

## Contribution

It presents detailed observations of a minifilament eruption and its magnetic flux evolution, highlighting the magnetic flux cancellation process prior to eruption.

## Key findings

- Minifilament forms around 15:50 UT and erupts at 22:08 UT.
- Positive magnetic flux decreases prior to eruption due to flux cancellation.
- Eruption results from magnetic flux changes beneath the minifilament.

## Abstract

We observe a coronal jet around 22:08 UT on 23 rd March of 2017, in a quiet region towards the north-east of the solar disk. A minifilament eruption leads to this jet. We analyze dynamics of the minifilament from its formation until its eruption. We observe that the minifilament starts forming around 15:50 UT. Then at a later time, it disappears but again appears and finally erupts as a blowout jet around 22:08 UT. We study the evolution of photospheric magnetic field beneath the minifilament. Initially, we observe subsequent increase and decrease of positive magnetic flux. Prior to the initiation of the eruption, positive magnetic flux shows a continuous decrease until the minifilament disappears. The positive magnetic flux increases and decreases due to new positive flux emergence and cancellation of positive magnetic flux with negative magnetic flux respectively.
