Fig. 6From: The 17 March 2015 storm: the associated magnetic flux rope structure and the storm developmentOrientation in the YZ plane of the axial field estimated for each of the flux rope models. For toroidal flux rope models, cases of the right-handed and left-handed are shown by red and blue arrows. For cylindrical flux rope model, only one case is shown because the orientations are close to each otherBack to article page
