The Impact of the 2024 Mother's Day Storm on Aircraft Surveillance Across Europe
Space Weather, Volume 23, Issue 12, December 2025.Abstract The Mother's day storm from 10–13 May 2024 is one of the most extreme space weather events recorded in recent decades and triggered a strong ionospheric response with various impacts on communication and navigation systems. In this study the impact on the aviation sector, and more specifically air traffic management, is investigated with ...

Magnetopause Reconnection Voltages During the Voyager 2 Flyby of Uranus
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract Uranus' magnetosphere presents a unique system to examine global magnetic reconnection processes due to its location far from the Sun. We assess reconnection effectiveness during Voyager 2's Uranus flyby, using a physics‐based analytical model to calculate reconnection voltages applied to the magnetopause.

North‐South Shear Along the West‐Lut Fault, Iran, Imaged From Burst Overlap InSAR
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.Abstract High‐resolution geodetic measurements of crustal deformation from InSAR provide crucial constraints on a region's tectonics, geodynamics, and seismic hazard. However, space‐based InSAR usually only provides good constraints on horizontal displacement in the east‐west direction, with the north‐south component typically provided by low ...
