TL;DR: In this article, the authors quantitatively analyze magnetic flux erosion using combined, multipoint observations of the same magnetic flux rope by STEREO A, B, ACE, WIND and THEMIS on November 19-20, 2007.

TL;DR: In this article, the authors quantify and provide a broader context to this process, starting from 263 tabulated interplanetary coronal mass ejections, including MCs, observed over a time period covering 17 years and at a distance of 1 AU from the Sun with Wind (1995-2008) and the two STEREO (2009-2012) spacecraft.

TL;DR: In this paper, the authors studied the link between an expanding coronal shock and the energetic particles measured near Earth during the ground level enhancement of 2012 May 17, and developed a new technique based on multipoint imaging to triangulate the three-dimensional (3D) expansion of the shock forming in the corona.
Journal ArticleDOI

TL;DR: Evidence for the predicted dust-free zone near the Sun is revealed and observations of the coronal streamer evolution confirm the large-scale topology of the solar corona, but also reveal that, as recently predicted, streamers are composed of yet smaller substreamers channelling continual density fluctuations at all visible scales.
