Magnetic Field Dynamics in MAAX Satellite's Circular Polar Orbit: A Magnetic Model Comparison

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Motivated by the unique high‐altitude polar orbit of the NASA Magnetosphere Auroral Asymmetry eXplorer (MAAX) mission and its Magnetometer Array Distributed on MAAX (MADMAAX), we examine the high‐altitude magnetic field environment and its response to solar wind conditions. Using a data set from the Polar satellite magnetometer, we investigate

Global Structure of the Cislunar Magnetotail and Its Evolution During Substorms

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract So far, the structure and dynamics of the terrestrial magnetotail have largely been investigated within 31RE $31{R}_{E}$ (RE ${R}_{E}$ is the Earth's radius) because of the lack of in‐situ observations beyond that distance, as well as limitations of earlier empirical models.

The Impact of OMNI Data Accuracy on Thermospheric Neutral Density Simulations at Grid Cell Resolutions

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract As physics‐based global magnetosphere‐ionosphere‐thermosphere models enter operations for space weather forecasting, it is imperative that the sources of uncertainty in model outputs are thoroughly investigated. Global magnetosphere models rely on a set of input solar wind conditions to drive the model; such inputs are often propagated from ...

Ionospheric Scintillation and Geomagnetic Disturbance Caused by Space Hurricanes

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract A space hurricane is a large‐scale, cyclone‐shaped aurora characterized by a rotating magnetic structure and shears in plasma convection, driven by high‐latitude magnetic reconnection. It typically forms near the magnetic poles in summertime, providing an efficient energy transport channel from the solar wind to the Earth's magnetosphere under

Beacon2Science: Enhancing STEREO/HI Beacon Data With Machine Learning for Efficient CME Tracking

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract Observing and forecasting coronal mass ejections (CMEs) in real‐time is crucial due to the strong geomagnetic storms they can generate that can have a potentially damaging effect, for example, on satellites and electrical devices. With its near‐real‐time availability, Solar TErrestrial RElations Observatory‐heliospheric imagers (STEREO/HI ...

Analog Ensemble Forecasts of Solar Wind Parameters: Quantification of the Predictability and Time‐Domain Spectral Performance

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract Forecasting multiscale properties of the solar wind is one of the important aspects of space weather prediction as mesoscales, larger than 1 min, can affect the magnetosphere. Amongst forecasting techniques, the analog ensemble (AnEn) method allows the forecast of a quantity from its past behavior, is easy and quick to implement, and results ...

Heliospheric Turbulence: Presidential Budget Request Offers a Bleak Forecast for Space Weather Research

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract The presidential budget request (PBR) for fiscal year 2026 in the United States recommends a cut in NASA science funding by more than 45% and the cancellation of a dozen active missions and several missions in design or formulation. Funding reductions at the National Science Foundation (NSF) are even larger and include cancellations of ...
