Fig. 2: One solar jet event on 2020 January 23.
From: The origin of interplanetary switchbacks in reconnection at chromospheric network boundaries
a, Position of the jet on the AIA 304 Å image. The magnetic flux tube (in yellow) shows the position of the jet. The black curves superposed on the background image represent the boundaries of the chromospheric network. The white rectangle marks the areas shown in b and c. b, The magnetic field geometry obtained by linear force-free field extrapolation in the vicinity of the jet. The colour along the magnetic field lines shows the amplitude of the local magnetic field from low (blue) to high (red). The bottom ends of the magnetic field lines connect to the HMI magnetogram, with white and black representing positive and negative magnetic polarity. The yellow tube represents the corresponding magnetic flux tube. c, HMI magnetogram and multi-waveband AIA images from 2020 January 23 16:41:41 arranged by the peak temperatures of the response functions. The HMI magnetogram is the same as in b. The bright areas in AIA images show the morphology of the jet.
