【 摘 要 】

Jets of all sizes are frequent magnetically channeled narrow eruptions. They occur in various solar environments: quiet regions, coronal holes and active regions. All coronal jets observed in UV, 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. We found in on disk quiet regions and coronal holes that coronal jets originate at a neutral line between dominant-polarity flux and a patch of canceling minority-polarity flux.
