Magnetic field disturbances in the sheath region of a super-sonic interplanetary magnetic cloud [PDF]
Annales Geophysicae, 2008 It is well-known that interplanetary magnetic clouds can cause strong geomagnetic storms due to the high magnetic field magnitude in their interior, especially if there is a large negative Bz component present.

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.Abstract This study statistically analyzes the electron precipitation patterns from 40 to 600 keV on dawnside and duskside and their correlations with geomagnetic activities and solar wind conditions based on Low‐Earth Orbit Fengyun‐3E (FY‐3E) satellite during July 2021 to May 2024.

Frontiers in Astronomy and Space Sciences, 2021 We investigate here the magnetic properties of a large-scale magnetic flux rope related to a coronal mass ejection (CME) that erupted from the Sun on September 12, 2014 and produced a well-defined flux rope in interplanetary space on September 14–15 ...

Slow Solar Wind: Origin in an Independent Small‐Scale Solar Dynamo
Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract Separation of the solar wind (SW) into three flow types (coronal mass ejections (CMEs), high speed streams (HSSs), and slow solar wind (SSW)) reveals an inverse relationship between the percentage of time Earth spends in SSW during a year and its annually averaged magnetic field strength (B).

Conjugate auroras and the interplanetary magnetic field [PDF]
Journal of Geophysical Research: Space Physics, 1997 Earlier results from analyses of auroral all‐sky data obtained on several series of conjugate flights along the College, Alaska, magnetic meridian are reevaluated, and it is suggested that while the diffuse aurora is conjugate, the discrete aurora is nonconjugate but still on closed field lines.

Statistical Analysis of the Short Large‐Amplitude Magnetic Structures: Evolution and Ion Resonance
Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract Short large‐amplitude magnetic structures (SLAMS) play a fundamental role in the formation and energy conversion of the collisionless shock. Nevertheless, the evolution and the ion dynamics inside SLAMS are still unclear. In this study, we performed a superposed analysis of SLAMS near the Earth's bow shock to investigate their properties and ...

Can an interplanetary magnetic field reach the surface of Venus? [PDF]
Annales Geophysicae, 2018 We address the question of whether there is a possibility of an interplanetary magnetic field reaching Venus' surface by magnetic diffusion across the ionosphere.

Upstream IMF Influence on Closed Magnetic Field Orientation on Mars
Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract Closed magnetic fields play an important role in plasma transport and atmospheric escape from the Martian dayside ionosphere. Leveraging in‐situ magnetic field data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we conduct a statistical analysis of closed magnetic field behavior under varying upstream conditions. Our findings
