Fan-shaped jet close to a light bridge

Aims. On the Sun, jets in light bridges (LBs) are frequently observed with high-resolution instruments. The respective roles played by convection and magnetic field triggering such not yet clear. Methods. We report a small fan-shaped jet along LB 1.6m Goode Solar Telescope (GST) TiO Broadband Filter Imager (BFI), Visible Imaging Spectrometer (VIS) H α , Near-InfraRed Spectropolarimeter (NIRIS), Stokes parameters. high spatial temporal resolution of those instruments allowed us to analyze features identified during event. By constructing Dopplergrams, we found that plasma is first moving upward, whereas second phase jet, flowing back. Working time slice diagrams, investigated propagation-projected speed fan its bright base. Results. developed within few minutes, diverging beams. At base, point was slipping ultimately invaded umbra sunspot. profiles points enhanced intensity wings, similarly case Ellerman bombs. Co-temporally, extreme ultraviolet (EUV) brightenings at front dark material moved same as fan, leading propose compressed heated ambient extremities corona. Conclusions. Our multi-wavelength analysis indicates could result from reconnection across highly low chromosphere, an apparent motion LB. However, did find any opposite polarity would typically be expected configuration. therefore discuss other plausible physical mechanisms, based on waves convection, may have triggered
