Magnetospheric access for solar protons during the January 2005 SEP event
Journal of Space Weather and Space Climate, 2018 The early phase of the extraordinary solar energetic particle 20 January, 2005 event having the highest peak flux of any SEP in the past 50 years of protons with energies > 100 MeV is studied.

Propagation of low frequency geomagnetic field fluctuations in Antarctica: comparison between two polar cap stations [PDF]
Annales Geophysicae, 2007 We conduct a statistical analysis of the coherence and phase difference of low frequency geomagnetic fluctuations between two Antarctic stations, Mario Zucchelli Station (geographic coordinates: 74.7° S, 164.1° E; corrected geomagnetic ...

A review of heliospheric plasma sheets and their impacts on planetary space weather
地球与行星物理论评, 2021 The heliospheric plasma sheet (HPS) is generally viewed as a structure straddling a heliospheric current sheet (HCS) where the interplanetary magnetic field changes polarity. It is generally characterized by enhanced density, depressed magnetic field and

32. Interplanetary magnetic field [PDF]
Symposium - International Astronomical Union, 1958 The magnetic field outside the sun (interplanetary magnetic field) is certainly far from a dipole field. A model of it has recently been suggested (Tellus,8, 1, 1956). This model is in agreement with cosmic ray and magnetic storm data and reconcilable with the coronal ray structure. Some possibilities to check the model are discussed.

Revised time-of-flight calculations for high-latitude geomagnetic pulsations using a realistic magnetospheric magnetic field model [PDF]
, 2005 We present a simple time-of-flight analysis of Alfvén pulsations standing on closed terrestrial magnetic field lines. The technique employed in this study in order to calculate the characteristic period of such oscillations builds upon earlier time-of ...

MHD waves at the pre-front of interplanetary shocks on September 6 and 7, 2017
Solar-Terrestrial PhysicsWe analyze strong space weather disturbances during first ten days of September 2017, using the geomagnetic Dst index, parameters of normals to interplanetary shock fronts, direct measurements of interplanetary magnetic field, solar wind, and cosmic ray ...

Evolution of the interplanetary magnetic field [PDF]
, 1994 Remote observations of magnetic field topologies in the solar corona and in situ observations of the solar wind and interplanetary magnetic field (IMF) in interplanetary space are used to examine the temporal evolution of the spatial distribution of open and closed field regions emanating from the Sun.

Acceleration of an interplanetary shock through the magnetosheath: a global hybrid simulation
Frontiers in Astronomy and Space SciencesAccording to most observations and simulations, interplanetary shocks slow down when they propagate through the magnetosheath. In this article, we present results from a self-consistent global hybrid PIC simulation of an interplanetary shock which, by ...

Termination Shock Asymmetries as Seen by the Voyager Spacecraft: The Role of the Interstellar Magnetic Field and Neutral Hydrogen [PDF]
, 2007 We show that asymmetries of the termination shock due to the influence of the interstellar magnetic field (ISMF) are considerably smaller in the presence of neutral hydrogen atoms, which tend to symmetrize the heliopause, the termination shock, and the ...
