Imaging the Transition from Corona to Solar Wind
Abstract
The region around the Alfvén surface -- the last frontier of the solar system -- is largely unexplored, mostly because of the difficulty of detecting the surface itself. Many important transitions happen between the mid-to-outer corona and the innermost heliosphere, including: the transition to superAlfvénic flow; the transition from structured, highly anisotropic structure to nearly isotropic turbulent structures; and the formation of identifiable, separable fast and slow wind streams. We will report new results from two recent imaging campaigns -- one with STEREO and one with SOHO/LASCO (coincidentally performed on the 20th anniversary of the first SOHO campaign) -- to explore and image the transition to turbulent flow and the outer boundary of the corona.
