Statistical Study of Geoeffective Fe XV 28.4 nm Emission Bursts and Their Influence on Ionospheric Total Electron Content During the Late Phase of Solar Flares

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract Recent studies have demonstrated that warm coronal emissions during the extreme ultraviolet late phase (ELP) of X‐class solar flares can be sufficiently strong to also affect electron density in the Earth's ionosphere. The Fe XV 28.4 nm line was identified as one of the most geoeffective emissions produced during the ELP.

Bed Topography and Subglacial Conditions of Denman Glacier, East Antarctica: Insights From Magnetotelluric Data and Interdisciplinary Studies

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Understanding the basal conditions of East Antarctica's outlet glaciers is critical for accurately modeling future ice‐sheet evolution. Denman Glacier, one of the continent's fastest‐flowing glaciers, has been identified in bed‐topography models as occupying the deepest continental trough on Earth, potentially acting as a major outlet of the ...

Quantifying Errors in the Midpoint Transform Applied to Oblique Ionograms

Radio Science, Volume 61, Issue 7, July 2026.
Abstract It is important to specify the state of the ionosphere for Over‐the‐Horizon communications and surveillance. Both vertical and oblique ionograms provide valuable data to this end. Oblique ionograms can probe the ionosphere in locations where it would be impractical to build a vertical ionosonde, but their measurements are not straightforward ...

Application of Deep Learning and Explainable AI to NIR Auroral Detection in Satellite Time‐Series Images

Space Weather, Volume 24, Issue 7, July 2026.
Abstract In this study, we employ a deep learning approach to detect auroras from near‐infrared (NIR) sequential images captured by the satellite‐based imager, the Enhanced Polar Outflow Probe (e‐POP)/Fast Auroral Imager (FAI). We also apply the Eigen‐Class Activation Map (Eigen‐CAM), an explainable AI technique in a broad sense, as a post‐hoc ...

Global Effect of Long‐Lasting 07–12 October 2024 Geomagnetic Storms During the Transition From a Strong (G3) to a Severe (G4) on the Geomagnetic Field and Ionospheric Parameters Distribution

Space Weather, Volume 24, Issue 7, July 2026.
Abstract This study investigates the co‐evolution of geomagnetic field disturbances with ionospheric parameters and their characteristic latitudinal signatures by conducting a location and time‐dependent analysis of the 07–12 October 2024 events, to fill crucial gaps in understanding the coupled response of the magnetosphere‐ionosphere system.
