Evidence for a Circumsolar Dust Ring Near Mercury\textquoterights Orbit To test a technique to be used on the white-light imager onboard the recently launched Parker Solar Probe mission, we performed a numerical differentiation of the brightness profiles along the photometric axis of the F-corona models that are derived from STEREO Ahead Sun Earth Connection Heliospheric Investigation observations recorded with the HI-1 instrument between 2007 December and 2014 March. We found a consistent pattern in the derivatives that can be observed from any S/C longitude between about 18\textdegree and 2 ...

White-light coronal and heliospheric imagers observe scattering of photospheric light from both dust particles (the F-Corona) and free electrons in the corona (the K-corona). The separation of the two coronae is thus vitally important to reveal the faint K-coronal structures (e.g., streamers, co-rotating interaction regions, coronal mass ejections, etc.). However, the separation of the two coronae is very difficult, so we are content in defining a background corona that contains the F- and as little K- as possible. For bo ...

INBOUND WAVES IN THE SOLAR CORONA: A DIRECT INDICATOR OF ALFV\ EN SURFACE LOCATION The tenuous supersonic solar wind that streams from the top of the corona passes through a natural boundary\textemdashthe Alfv\ en surface\textemdashthat marks the causal disconnection of individual packets of plasma and magnetic flux from the Sun itself. The Alfv\ en surface is the locus where the radial motion of the accelerating solar wind passes the radial Alfv\ en speed, and therefore any displacement of material cannot carry information back down into the corona. It is thus the natural outer boundary of the solar co ...
