Formation of a strong southward IMF near the solar maximum of cycle 23 [PDF]
Annales Geophysicae, 2004 We analyzed observations of the solar activities and the solar wind parameters associated with large geomagnetic storms near the maximum of solar cycle 23.

Sources of interplanetary shocks [PDF]
Advances in Space Research, 1995 Abstract The sources of interplanetary shocks are reviewed from the standpoint of today's knowledge. Recent progress from both new and accumulated observations and models indicates that contributions from the two major sources of the shocks: CMEs and stream interactions, have distinctive radial, latitudinal and temporal dependencies.

Evolution of the Suprathermal Proton Population at Interplanetary Shocks
Astronomical Journal, 2019 We investigate the evolution of the suprathermal (ST) proton population as interplanetary shocks cross 1 au. The variability of the ST proton intensities and energy spectra upstream of the shocks is analyzed in terms of the shock parameters, upstream ...

Efficiency of particle acceleration at interplanetary shocks: Statistical study of STEREO observations [PDF]
, 2016 Context. Among others, shocks are known to be accelerators of energetic charged particles. However, many questions regarding the acceleration efficiency and the required conditions are not fully understood. In particular, the acceleration of electrons by

Space Weather, 2018 The occurrence of geomagnetically induced currents (GICs) poses serious threats to modern technological infrastructure. Large GICs result from sharp variations of the geomagnetic field (dB/dt) caused by changes of large‐scale magnetospheric and ...

What causes the variations of the peak intensity of CIR accelerated energetic ion fluxes? [PDF]
Annales Geophysicae, 1998 The variation of the peak intensity of energetic ions accelerated at CIR related shocks in the interplanetary medium as observed by instruments on board of ULYSSES during its pass towards the south polar region and from the north polar region back to ...

Interplanetary Signatures during the 1972 Early August Solar Storms
The Astrophysical Journal, 2023 In 1972, early August, a series of interplanetary shocks were observed in the heliosphere from 0.8 to 2.2 au. These shocks were attributed to a series of brilliant flares and plasma clouds since at that time coronal mass ejections (CMEs) and their ...
