## TL;DR

This study analyzes recurrent solar jets originating from a satellite sunspot, revealing their blowout nature, association with CMEs, and the magnetic field dynamics involved, providing insights into jet-CME relationships.

## Contribution

It presents a detailed analysis of satellite sunspot-triggered recurrent jets, highlighting the blowout characteristics and their connection to coronal mass ejections, which is a novel observation.

## Key findings

- Approximately 30% of blowout jets developed into CMEs.
- Blowout jets are faster, larger, and more energetic than standard jets.
- Most blowout jets were associated with flares or brightening at the base.

## Abstract

In this paper,we report a detailed analysis of recurrent jets originated from a location with emerging, canceling and converging negative magnetic field at the east edge of NOAA active region AR11166 from 2011 March 09 to 10. The event presented several interesting features. First, a satellite sunspot appeared and collided with a pre-existing opposite polarity magnetic field and caused a recurrent solar jet event. Second, the evolution of the jets showed blowout-like nature and standard characteristics. Third, the satellite sunspot exhibited a motion toward southeast of AR11166 and merged with the emerging flux near the opposite polarity sunspot penumbra, which afterward, due to flux convergence and cancellation episodes, caused recurrent jets. Fourth, three of the blowout jets associated with coronal mass ejections (CMEs), were observed from field of view of the Solar Terrestrial Relations Observatory. Fifth, almost all the blowout jet eruptions were accompanied with flares or with more intense brightening in the jet base region, while almost standard jets did not manifest such obvious feature during eruptions. The most important, the blowout jets were inclined to faster and larger scale than the standard jets. The standard jets instead were inclined to relative longer-lasting. The obvious shearing and twisting motions of the magnetic field may be interpreted as due to the shearing and twisting motions for a blowout jet eruption. From the statistical results, about 30% blowout jets directly developed into CMEs. It suggests that the blowout jets and CMEs should have a tight relationship.
