Predicting CME Arrivals From L5 Heliospheric Imagers: The Impact of HI Track Length
Space Weather, Volume 24, Issue 5, May 2026.Abstract The Solar TErrestrial RElations Observatory (STEREO) mission has laid a foundation for advancing real‐time space weather forecasting by enabling the evaluation of heliospheric imager (HI) data for predicting coronal mass ejection (CME) arrivals at Earth.

Space Weather, Volume 24, Issue 5, May 2026.Abstract We present a validation of our recently proposed non‐conventional method, Constant Acceleration Accounted Perspective (CAAP), for estimating the instantaneous expansion speed of coronal mass ejection (CMEs), even when only single‐point in situ observations are available. This validation is enabled by the radial alignment of Solar Orbiter (SolO)

A Robust Empirical Relationship Between Speed and Turbulence Energy in the Near‐Earth Solar Wind
Space Weather, Volume 24, Issue 5, May 2026.Abstract The connection between turbulence and solar‐wind acceleration, long known in space physics, is further developed in this study by establishing a robust empirical law that relates the bulk‐flow speed to the magnetohydrodynamic‐scale fluctuation energy in the plasma. The model is based on analysis of 25 years of near‐Earth observations by NASA's

Updates, Examples and Validation of the Global Ionosphere Thermosphere Model
Space Weather, Volume 24, Issue 5, May 2026.Abstract This study provides an updated description, example simulations, and validation of the Global Ionosphere Thermosphere Model (GITM). The updates to GITM include using an exothermic semi‐implicit chemistry scheme that no longer requires an altitude dependent heating efficiency; an ionospheric wind‐driven dynamo; improved neutral, ion, and ...

Storm‐Time Dst Forecast: An Innovative Approach
Space Weather, Volume 24, Issue 5, May 2026.Abstract One of the most persistent challenges in the space weather field is predicting the storm‐time response of the geospace without knowing the predicted drivers in the solar wind. Here, a new pattern recognition algorithm is developed to predict storm‐time Dst index from 1 hr to ∼4.5 days into the future. Storm‐time Dst patterns (or reference Dst)

Analysis of Chorus Wave Power on Burst‐Mode Timescales During the Van Allen Probes Era
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract Interactions between whistler‐mode chorus waves and electrons are a key driver of dynamics in Earth's radiation belts. These global dynamics are often described using Fokker‐Planck diffusion models. Whilst, in many cases, such models effectively describe the large scale changes within the region, they often rely upon spatially and temporally ...
