Deterministic Propagation of Suprathermal Ions Through the Heliosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The PEPSSI instrument onboard New Horizons is sampling the energy range that bridges pickup and suprathermal He+ ${\mathrm{H}\mathrm{e}}^{+}$ ions for the first time in the outer heliosphere. New Horizons repeatedly encountered structures beyond 30 au that we interpret as the spiral of a corotating interaction region (CIR) for an extended ...

Variability in Saturn's bow shock and magnetopause from pioneer and voyager: Probabilistic predictions and initial observations by Cassini [PDF]

, 2005
Probability distributions for the location of the Saturnian bow shock and magnetopause have been derived by extrapolating observations of dynamic solar wind pressures to the position of Saturn's orbit. These observations are those made by the Pioneer 11,

Interplanetary Tracking of the 23 March 2024 CME: Computer Tomographic Analyses of IPS, White‐Light, and Type II Radio Burst Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract We analyze the propagation of a coronal mass ejection (CME) observed on 23 March 2024, at 01:25 UT by SOHO/LASCO using a multi‐instrument and multi‐method approach. The study combines Interplanetary Scintillation (IPS), type II radio bursts, white‐light, in‐situ observations, and 3D tomographic reconstruction of the inner heliospheric density.

Magnetosphere

Eos, Transactions American Geophysical Union, 1971
This report on progress in the magnetosphere covers the calendar years 1967–1970 inclusive. Bibliographical coverage is also for the period 1967–1970: therefore, results presented at conferences but not yet available in published form may be cited.The topic of the magnetosphere has been divided into five sections: magnetopause; magnetosphere structure,

Magnetic Signature of the Corona Lava Tube (Lanzarote, Canary Islands), a Lunar and Martian Planetary Analog

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Lava tubes and caves are key exploration targets on the Moon and Mars due to their potential to serve as natural infrastructure for future crewed missions. However, identifying these structures efficiently and reliably remains a major challenge.

Bregman Wave Distribution Function Method

Radio Science, Volume 61, Issue 7, July 2026.
Abstract This study proposes a wave distribution function (WDF) estimation method based on minimizing the Bregman divergence in the function space. The proposed method is entirely data‐driven and requires no hyperparameter tuning during the estimation process. It can be regarded as an extension of the maximum entropy method.

Forecasting Local Geomagnetic Disturbances Using Machine Learning: A Multi‐Station Approach

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Geomagnetic indices such as SYM‐H capture global disturbances but fail to resolve regional impacts critical for infrastructure resilience. We present a machine learning model to forecast the Local Disturbance Index (LDi), a validated regional geomagnetic index.

Review of ionospheric effects of solar wind magnetosphere coupling in the context of the expanding contracting polar cap boundary model [PDF]

, 2006
This paper reviews the coupling between the solar wind, magnetosphere and ionosphere. The coupling between the solar wind and Earth’s magnetosphere is controlled by the orientation of the Interplanetary Magnetic Field (IMF).

Magnetosphere

Eos, Transactions American Geophysical Union, 1991
Research on the terrestrial magnetosphere, above 500 km, continues to focus on how energy gets from the solar wind into the magnetosphere and how it circulates through the magnetosphere. The prime candidate for energy coupling has long been magnetic merging in which the magnetic field that the solar wind carries from the Sun merges with the geomagnetic
