Multilayered Sporadic‐E Response to the Annular Solar Eclipse on June 21, 2020
Space Weather, 2021 A moon shadow of annular solar eclipse passed through East Asia in the afternoon on June 21, 2020, which was a good opportunity to study the rapid ionospheric response to the solar radiation variations. In the study, the high‐frequency echoes recorded by

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract A set of fresh Equatorial Plasma Bubbles (EPBs) formed during pre‐sunrise hours in the Southeast Asian sector amid the recovery phase of May 2024 geomagnetic storm. They offered new insights into their formation mechanism. This study used Total Electron Content (TEC) and Rate of TEC Index maps over Indonesia, along with ionosondes in Thailand ...

YOLO‐Based Detection and Localization of Rocket Induced Traveling Ionospheric Disturbances
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract During rocket launches, atmospheric disturbances significantly impact the ionosphere, generating Traveling Ionospheric Disturbances (TIDs). These disturbances can affect radio communications and navigation systems and may pose risks to high‐speed aerospace vehicles.

Latitudinal Dependence of the Geomagnetic and Solar Activity Effect on Sporadic‐E Layer
Space Weather, Volume 24, Issue 8, August 2026.Abstract Based on the global COSMIC occultation data, the latitudinal dependence of the geomagnetic and solar activity effect on the sporadic‐E (Es) layer is statically investigated. At middle geomagnetic latitudes, Es occurrence rates generally decrease with increasing solar activity, except during winter and spring in the Southern Hemisphere.
