Observations of the Magnetopause Reconnection Ion Diffusion Region With High‐Density O+ Ions During the May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Based on high‐resolution measurements from NASA's Magnetospheric Multiscale mission (MMS), we present the first direct observation of an ion diffusion region (IDR) with high number density O+ ions within dayside magnetopause reconnection during the May 2024 superstorm. The O+ ion density reaches a high value of ∼3.3 cm−3.

First Quantitative Results on the Response of Green and Red Line Dayglow Emissions to Solar Flares of Different Magnitudes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Flares originate from the impulsive release of magnetic energy in the solar atmosphere. The rise in X‐ray flux enhances ionization/electron content in the upper atmosphere, modifying the photochemical and dynamical processes that govern the ionosphere‐thermosphere behavior.

Sudden Ionospheric Disturbances Generated by Solar Flares—Not so Sudden?

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract It is known that solar flares generate instantaneous ionization enhancement, referred to as sudden ionospheric disturbance (SID), that occurs simultaneously across the entire dayside. In this work, we use high‐rate 1‐s data of total electron content (TEC) to analyse ionospheric response to 13 solar flares that occurred in 2003–2023.

Observations and Simulation of Thermospheric Composition Changes During the 14 October 2023 Solar Eclipse

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study presents a full‐period imaging of the thermospheric composition response to the 14 October 2023 annular solar eclipse, combining GOLD (Global‐scale Observations of the Limb and Disk) far‐ultraviolet observations with solar‐irradiance‐driven WACCM‐X (Whole Atmosphere Community Climate Model with thermosphere–ionosphere extension ...
