Resumen:
Coronal ejective events, in particular coronal mass ejections (CMEs), expel mass and mag-netic field from the Sun into the interplanetary medium. Interplanetary coronal mass ejections (ICMEs), a subset of which are known as magnetic clouds (MCs), are considered to be the interplanetary counterparts of CMEs. In general, the association between these phenomena is determined taking into account the CME source region position on the Sun, the time de-lay expected between both events, and/or by comparing the orientation of the coronal and interplanetary "in situ" magnetic fields. Several recent studies have shown this connection in a more quantitative way, combining multi-wavelength remote sensing and "in situ" observa-tions, together with magnetic field modeling in both domains. This link is based, in general, in the computation and comparison of magneto-hydrodynamic invariants, such as magnetic fluxes and helicity. We will review the trends found in these later studies and will discuss how this kind of analysis can help us to constrain our modeling, both at the coronal level and in the interplanetary space.
