Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...

Neutral Wind Dynamics in High‐Latitude Regions During the 17 March 2013 Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract Neutral winds play a critical role in transporting mass, momentum, and energy throughout the upper atmosphere. During geomagnetic storms, momentum is transferred to the thermosphere primarily through ion–neutral collisions, along with other forces. This study investigates high‐latitude neutral wind dynamics during the 17 March 2013 storm using

Multiple Flux Rope Dynamics: MMS Observations and Reconstruction Results
The Astrophysical JournalA series of six ion-scale magnetic flux ropes (FR1–6) and a thin current sheet, encountered by Magnetospheric Multiscale spacecraft in the magnetosheath side of the dayside magnetopause boundary layer, are studied for multiple flux rope dynamics in terms

A Overview of Interplanetary Scintillation Method for Studying Solar Wind Physics
Journal of Astronomy and Space Sciences, 1988 Interplanetary scintillation is the fluctuation produced in the apparent brightness of a radio source, due to refractive effects in the turbulent solar wind flowing from the sun. If this medium is illuminated coherently, analysis of the spatial and temporal properties of the radiation reaching the earth allows the stochastic properties of the medium to

Space Weather, Volume 24, Issue 8, August 2026.Abstract Auroral precipitation plays a key role in coupling the Magnetosphere–Ionosphere–Thermosphere system by modifying ionospheric conductance, currents, atmospheric heating, and upper‐atmospheric dynamics. Leveraging 17 years of electron spectrum data from the Defense Meteorological Satellite Program (DMSP), we developed a Machine Learning‐based ...

Assessment of Spacecraft Internal Charging in the Earth's Outer Radiation Belt
Space Weather, Volume 24, Issue 8, August 2026.Abstract The internal charging effects triggered by energetic (>100 keV) electrons in the Earth's radiation belts can cause anomalies and failures of electronic components aboard spacecraft. Given the critical importance of safeguarding space assets, it is essential to estimate internal charging risks, which depend highly on the distribution of ...

Forecast and Nowcast Solar Energetic Particles (SEP) Radiation Doses in Near Earth/Moon Space
Space Weather, Volume 24, Issue 8, August 2026.Abstract Solar energetic particle (SEP) events pose a critical radiation hazard to human space exploration, and extreme SEPs must be mitigated operationally to avoid serious health impacts. Accurate prediction of SEP‐induced radiation exposure is essential to ensure mission safety.

Solar-cycle variations of interaction regions: In-ecliptic observations from 1 to 5 AU [PDF]
Geofísica Internacional, 2000 We study a combined set of 97 interaction regions detected by Pioneers 10 and 11, Voyagers 1 and 2, and Ulysses from 1 to 5 AU during their respective journeys to Jupiter at different phases of the solar cycle.

AI Based Velocity Calibration for Cassini's Cosmic Dust Analyzer (CDA)
Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract This paper presents a novel AI‐based velocity calibration method for the Cosmic Dust Analyzer (CDA) onboard the Cassini spacecraft, in particular for impacts on the large Impact Ionization Detector (IID). The legacy polynomial calibration function, derived from laboratory measurements at a dust accelerator facility, assigns a velocity ...

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract The Spectral Irradiance Monitor (SIM), on board the Solar Radiation and Climate Experiment (SORCE) test satellite operated for 17 years: from February 2003 to February 2020, measuring the Solar Spectral Irradiance from 200 to 2,400 nm. The unavoidable instrument degradation was tracked and corrected based on a measurement equation derived from
