Filamentary Structures in the Solar Corona
Richard Woo
An important development with radio occultation measurements has been the discovery of extensive spatial structuring in the outer corona with the finest filamentary structures of kilometer scale size. In this paper, we will describe these observations and present the latest results. The latter include evidence for continual reconnection all over the Sun at the base of the corona, which unifies observations of small- and large scale structure of the outer corona, and provides insight into the connection between coronal and photospheric fields. The filamentary structures in the outer corona, which presumably trace the open magnetic field lines, are found to be predominantly radial, reinforcing similar earlier conclusions based on measurements of large-scale structure.
