Response of the magnetosphere-ionosphere system to a sudden southward turning of interplanetary magnetic field
[1] A sudden southward turning of interplanetary magnetic field (IMF) is simulated by the University of Michigan’s BATS-R-US model. The main goal of this study is to determine the time delay as well as physical processes between when an IMF discontinuity reaches the bow shock, when reconnection is initiated at the magnetopause, and when the ionosphere starts to react. While observations or empi...
متن کاملEvolution of an Interplanetary Shock in the Magnetosheath
We have prepared a short case study of a propagation of an interplanetary shock through the solar wind and magnetosheath. For this particular case, magnetic field and plasma measurements from four spacecraft in the solar wind and one in the magnetosheath are available. It allows us to determine both local and global shock planes and shock propagation speeds in the solar wind as well as local sh...

متن کاملInterplanetary Magnetic Field Structures out of the Ecliptic
New observations of the out-of-the ecliptic trajectories of type III solar radio bursts have been obtained from simultaneous direction finding measurements on two independent satellite experiments, IMP-6 with spin plane in the ecliptic, and RAE-2 with spin plane normal to the ecliptic. Burst exciter trajectories were observed which originated at the active region and then crossed the ecliptic p...
متن کاملA new reconstruction of the interplanetary magnetic field
We present a new reconstruction of the interplanetary magnetic field (IMF, B) for 1846–2012 with a full analysis of errors, based on the homogeneously constructed IDV(1d) composite of geomagnetic activity presented in Part 1 (Lockwood et al., 2013a). Analysis of the dependence of the commonly used geomagnetic indices on solar wind parameters is presented which helps explain why annual means of ...
