Effects of the September 2014 coronal mass ejection chain in the inner Solar System and the response of the Martian ionosphere

Sánchez-Cano, B.; Harada, Y.; Ippolito, A.

Context. During September 2014, intense solar activity led to a number of coronal mass ejections (CMEs) propagating in the heliosphere. The strong perturbation in the interplanetary magnetic field and the remarkable enhancements in the energetic particle fluxes accelerated by the shock waves associated with the CMEs affected the environments of th…

Instantaneous asymmetry of the Martian bow shock: A single- and dual-spacecraft study using MAVEN and Mars Express

Goetz, Charlotte; Gunell, Herbert; Nesbit-Östman, Sara

Aims. We study the instantaneous asymmetry of the Martian bow shock during a change in the direction of the interplanetary magnetic field (IMF) and for steady-state conditions. Specifically, we study the asymmetry with regard to the convective electric field and to the crustal fields of Mars. Methods. Two methods were used: First, a single-spacecr…
