Abstract We present a multi‐instrument analysis of the ionospheric response to the intense geomagnetic storm of 12 November 2025 over the American sector, with emphasis on the longitudinally asymmetric deformation, latitudinal expansion, and zonal drift reversal of equatorial plasma bubbles (EPBs).

Chorus Wave‐Induced Ionospheric Variability
Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere.

The paper presents data on long-lived (~20–40 min) meteor trails. We describe a group of soliton-type meteor trails expanding at transonic speeds. Radio sounding data evidences that the latter include ~7–8 min ionization trails.

The Daily Atmospheric Ionospheric Limb Imager (DAILI) CubeSat Experiment
Abstract The Daily Atmospheric Ionospheric Limb Imager (DAILI) (Daily Atmospheric and Ionospheric Limb Imager) mission utilized a 6U CubeSat, deployed at about 410 km altitude in a 51‐degree orbit, to make simultaneous daytime limb measurements in two colors; at 630 nm to measure the OI (630 nm) redline and at 765 nm to measure the O2 ${\mathrm{O}}_{2}$

Analyse von Turbulenz in Airglow-Imager-Daten mithilfe künstlicher Intelligenz
Trotz ihrer großen Bedeutung ist es eine Herausforderung, Schwerewellen in der UMLT (upper mesosphere / lower thermosphere) zu messen. Eine der wenigen Moglichkeiten bietet die OH*-Airglow-Schicht in einer Höhe von etwa 87 km.

Simultaneous Measurements of Variations in the Artificial Airglow and the Total Electron Content of the Ionosphere Caused by Powerful Radio Waves of "Sura'' Facility [PDF]
The results of simultaneous observations of variations in the artificial airglow in the red line of the optical spectrum of atomic oxygen (630 nm) and the total electron content (TEC) of the ionosphere measured along the propagation paths of the ...

Acoustic Wave Signatures of Earthquake Rupture Dynamics in the Upper Atmosphere
Abstract We perform three‐dimensional coupled earthquake‐atmosphere numerical simulations that integrate dynamic rupture, seismic wave propagation, and a compressible nonlinear atmospheric model to investigate how earthquake source parameters influence acoustic wave (AW) characteristics at 100–300 km altitude in the thermosphere.

Disentangling Stellar and Airglow Emission Lines from HST-COS Spectra [PDF]
H I Ly$\alpha$ (1215.67 \r{A}) and the O I triplet (1302.17, 1304.86, and 1306.03 \r{A}) are bright far-ultraviolet (FUV) emission lines that trace the stellar chromosphere.

Abstract Trans‐ionospheric high frequency (HF: 3–30 MHz) response to atmospheric gravity waves (GWs) is studied in the middle‐latitude ionosphere in relation to thunderstorm activity. SuperDARN HF radar observations are compared against the model simulations to quantify the impact of GW‐generated medium‐scale traveling ionospheric disturbances (MSTID ...
