Corotating drift-bounce resonance of plasmaspheric electron with poloidal ULF waves

Earth and Planetary Physics, 2017
The purpose of this paper is to understand how low energy plasmaspheric electrons respond to ULF waves excited by interplanetary shocks impinging on magnetosphere. It is found that both energy and pitch angle dispersed plasmaspheric electrons with energy

Spatial dependence of the local diffusion coefficient measured upstream of the November 12, 1978 interplanetary traveling shock [PDF]

Characteristics of wuprathermal particles accelerated by quasi-parallel interplanetary traveling shocks have been generally explained in terms of a first order Fermi mechanism.

Multiwavelength Study on Solar and Interplanetary Origins of the Strongest Geomagnetic Storm of Solar Cycle 23

, 2011
We study the solar sources of an intense geomagnetic storm of solar cycle 23 that occurred on 20 November 2003, based on ground- and space-based multiwavelength observations.

Evidence for superdiffusive shock acceleration at interplanetary shock waves

Journal of Physics: Conference Series, 2015
Recent analysis of time profiles of energetic particles accelerated at interplanetary shocks has shown evidence for superdiffusive transport upstream of the shock fronts, namely for a transport characterized by a particle mean square displacement that grows faster than linearly in time.

A Novel Blast Wave Solution for the Propagation of Coronal And Interplanetary Shocks

The Astrophysical Journal
Coronal mass ejections (CMEs) and their associated shock waves have severe space weather effects in the near-Earth space. Therefore, predicting the propagation and arrival time of the CME/shock is an important component of the space weather forecast.

The θBn problem: Determination of local magnetic parameters of interplanetary shocks from in situ IMF data [PDF]

Geofísica Internacional, 2001
The angle θBn is the angle between the upstream magnetic field and the shock normal direction and is important for many phenomena in interplanetary physics.

Plasma properties of driver gas following interplanetary shocks observed by ISEE-3 [PDF]

, 1982
Plasma fluid parameters calculated from solar wind and magnetic field data obtained on ISEE 3 were studied. The characteristic properties of driver gas following interplanetary shocks was determined.

Leaping and vortex motion of the shock aurora toward the late evening sector observed on 26 February 2023 [PDF]

Annales Geophysicae
On 26 February 2023, a shock aurora triggered by an interplanetary (IP) shock was observed in northern Scandinavia at 21 MLT (magnetic local time). Previously, ground-based observations of shock auroras have primarily been conducted on the dayside, where

Coronal Mass Ejections - Propagation Time and Associated Internal Energy

, 2010
In this paper, we analyze 91 coronal mass ejection (CME) events studied by Manoharan et al. (2004) and Gopalswamy and Xie (2008). These earth-directed CMEs are large (width $>$160$^\circ$) and cover a wide range of speeds ($\sim$120--2400 {\kmps}) in the

Search for a simultaneous signal from small transient events in the Pierre Auger Observatory and the Tupi muon telescopes

, 2011
We present results of a search for a possible signal from small scale solar transient events (such as flares and interplanetary shocks) as well as possible counterparts to Gamma-Ray Burst (GRB) observed simultaneously by the Tupi muon telescope Niteroi ...
