Investigations of a supra-arcade fan and termination shock above the top of the flare-loop system of the 2017 September 10 event
Lin, Jun; Raymond, John C.; Roussev, Ilia I. +4 more
On 2017 September 10, a major eruption on the west solar limb produced a class X-8.2 flare and a superfast coronal mass ejection (CME). During the eruptive process, the geometric topology of the erupting magnetic configuration presented a clear flare-current sheet (CS)-CME structure. Analysing the images and spectral data from the Solar Dynamics O…
Supergranular turbulence in the quiet Sun: Lagrangian coherent structures
Miranda, Rodrigo A.; Chian, Abraham C. -L.; Kusano, Kanya +6 more
The quiet Sun exhibits a wealth of magnetic activities that are fundamental for our understanding of solar magnetism. The magnetic fields in the quiet Sun are observed to evolve coherently, interacting with each other to form prominent structures as they are advected by photospheric flows. The aim of this paper is to study supergranular turbulence…
