【 摘 要 】

Coronal jets are frequent magnetically-channeled narrow eruptions. They occur in various solar environments: quiet regions, coronal holes and active regions. All coronal jets observed in EUV and X-ray images show a bright spire with a base brightening, also known as jet bright point (JBP). Recent studies show that coronal jets are driven by small-scale filament eruptions (e.g. Hong et al. 2011, Shen et al. 2012, Adams et al. 2014, Sterling et al 2015). We (Panesar et al. 2016b) found in on disk quiet regions that coronal jets originate at a neutral line between dominant-polarity flux and a patch of canceling minority-polarity flux.
