Abstract:
We provide evidence for the link between coronal ejective events and their interplanetary manifestations. We combine multi-wavelength remote sensing and in situ observations with the computation of the coronal and interplanetary magnetic fields using a standard linear force-free approach. The analysis and computations are applied to one of the smallest (on 11 May, 1998) and to a large ejecta (on 14 October, 1995), as well as to their related magnetic clouds. The connection between the coronal and interplanetary events is shown by comparing the magnetic helicity variation (pre- to post-eruption) in the corona to the helicity content in the associated magnetic clouds, and through the compatibility of other observational characteristics and computed quantities (e.g. magnetic flux) in both environments. Our results show that, within the uncertainties, the computed helicities are in good agreement. For the event on 11 May, 1998, the ejected magnetic flux and the flux in the associated interplanetary cloud also agree. Such quantitative analyses help to unambiguously identify the solar source region of magnetic clouds, and allow us to constrain theoretical models in both environments.
