Unveiling Ionospheric Response to the May 2024 Superstorm With Low‐Earth‐Orbit Satellite Observations

Space Weather, Volume 23, Issue 4, April 2025.
Abstract The space weather event on 10–11 May 2024 was a high‐impact geomagnetic storm, resulting in a SYM‐H index decrease to −518 nT, the lowest level registered in several decades. We investigated the response of the Earth's ionosphere during the main phase of this storm using a comprehensive data set of ionospheric observations (in situ plasma ...

Southwestern Tian Shan: 1. Deformation of Cenozoic Intra‐Montane Basins and Intervening Basement Ranges in Front of the Indian Mantle Indenter

Tectonics, Volume 44, Issue 4, April 2025.
Abstract A structural analysis of intra‐montane basins establishes the deformation field of the southwestern Tian Shan, that part of the Tian Shan that faces the Pamir and thus the deformation that the Indian mantle‐lithosphere indenter beneath the Pamir imposes—northward indentation and westward crustal collapse.

Southwestern Tian Shan: 2. Timing of Cenozoic Mountain Building, Intra‐Montane Basin Inversion, and Relation to Lithospheric Mantle Indentation

Tectonics, Volume 44, Issue 4, April 2025.
Abstract Cenozoic reactivation of the Paleozoic thick‐skinned fold‐thrust belt of the southwestern Tian Shan has—as the Afghan‐Tajik Basin inversion—been interpreted to be driven by Indian mantle‐lithosphere indentation beneath the Pamir. Herein, we date the reactivation and explore its temporal and spatial variations. Three structural domains emerged.

Should We Monitor Space Weather Effects on Surveillance Technologies Used in Air Traffic Management?—First Results

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Space weather events can disrupt satellite navigation, potentially compromising also the accuracy of real‐time flight tracking via Automatic Dependent Surveillance‐Broadcast (ADS‐B). This in turn could limit the situational awareness of pilots and reduce the efficiency of the air traffic management.
