Space Weather, Volume 23, Issue 5, May 2025.Abstract As society moves toward greater dependence on technology, understanding and predicting extreme Space Weather becomes increasingly important. Indeed, the complex, simultaneous interplay between multiple phenomena can unpack further insight into Space Weather effects.

Evidence of Confinement of Solar-energetic Particles to Interplanetary Magnetic Field Lines [PDF]
, 2011 We present new observations of solar-energetic particles (SEPs) associated with impulsive solar flares that show evidence for their confinement to interplanetary magnetic field lines.

Studying the Inner Heliosphere Using Radio Signals Transmitted From Spacecraft Orbiting Mars
Space Weather, Volume 23, Issue 5, May 2025.Abstract In this campaign, we used very long baseline interferometry (VLBI) radio telescopes to track the carrier radio signal transmitted from spacecraft orbiting Mars during the Mars solar conjunction. The campaign extended from September 6th $6\text{th}$ to November 6th $6\text{th}$ 2021 and targeted the Mars Express (MEX) and Tianwen‐1 (TIW ...

The interplanetary magnetic field [PDF]
Large-scale properties of the interplanetary magnetic field as determined by the solar wind velocity structure are examined. The various ways in which magnetic fields affect phenomena in the solar wind are summarized.

A new approach to detect the boundaries of interplanetary events [PDF]
Romanian Astronomical Journal, Vol.25, Pp.77-103, 2015, 2014 We propose a new method to scan the data and then to infer the boundaries of the interplanetary coronal mass ejections, especially the interplanetary events observed by \emph{Ulysses}. The local minima of the temperatures ratio measured by the spacecraft are used to scan and compute the potential boundaries of the interplanetary events.

The Propagation and Evolution of Polar Cap Patches During Auroral Substorm Activity
Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.Abstract Polar cap patches are islands of enhanced plasma density formed during intervals of southward interplanetary magnetic field (IMF). The present study examines the observations of polar cap patches during sequential auroral substorms that occurred on 9 September 2011.

The electromagnetic structure of interplanetary space [PDF]
A method to calculate the three-dimensional structure of the interplanetary magnetic field is presented. The integrations are based on magnetograph recordings of longitudinal magnetic fields in the solar photosphere. The program by Altschuler and Newkirk

Dependence of the High Latitude Middle Atmosphere Ionization on Structures in Interplanetary Space [PDF]
, 1984 The precipitation of high energetic electrons during and after strong geomagnetic storms into heights below 100 km in middle and subauroral latitudes is markedly modulated by the structure of the interplanetary magnetic field (IMF).

A case study of large-amplitude ULF waves in the Martian foreshock
Earth and Planetary Physics, 2020 Foreshock ultralow frequency (ULF) waves constitute a significant physical phenomenon in the plasma environment of terrestrial planets. The occurrence of these waves, associated with backstreaming particles reflected and accelerated at the bow shock ...

Relations between variability of the photospheric and interplanetary magnetic fields, solar wind and geomagnetic characteristics [PDF]
arXiv, 2018 Large scale solar magnetic field topology has a great influence on the structure of the corona, heliosphera and geomagnetic perturbations. Data obtained over the last three solar cycles have been analysed to reveal the relationships between the photospheric field measured along the line of sight by the WSO group at 30 levels of heliolatitudes from ...
