Abstract/Summary

Key Points We validate our proposed constant acceleration accounted perspective method for estimating the instantaneous expansion speed of coronal mass ejection (CMEs) Radial alignment of two spacecraft enabled simultaneous observations of the magnetic cloud center (at Wind) and trailing edge (at Solar Orbiter) Radially separated two spacecraft reveal that the properties of the CME substructures evolve significantly between the two locations
