Ionospheric Changes Following the Geomagnetic Storm of May 2024
A new study finds that unique ionospheric changes occurred in the upper atmosphere in response to the May 2024 geomagnetic superstorm.
Wave-Modulated Electron Loss Affects GPS Location Determination
Earth’s magnetosphere controls ionospheric total electron content modulation via plasma wave-induced electron loss impacting GPS spatial location determination.
Radar Reveals Electrical Activity in the Ionosphere
A new method could improve understanding of communication disruptions.
Ground-based Transmitters Cause Radiation Belt Electron Loss
A U.S. Navy transmitter in Australia produces wisps of electron loss as observed by the Colorado Inner Radiation Belt Experiment (CIRBE) CubeSat in Low Earth Orbit.
Unusual Occurrence of STEVE: An Aurora-Like Glow
STEVE is a mysterious purple-white arc near the aurora, typically seen after space disturbances called substorms. A new study reveals a rare STEVE event without a substorm, prompting questions about its origin.
From Sun to Earth: A New Network for Comprehensive Space Weather Monitoring
The Chinese Meridian Project combines hundreds of instruments for a detailed, three-dimensional view of the solar-terrestrial environment.
Impact of NASA’s GDC Measurements on Predicting Earth’s Upper Atmosphere
A new study finds that assimilating observations of the ionosphere and thermosphere reduces the error in model predictions more than modeling either one individually.
Radioamadores Foram Usados Para Obter Informações sobre a Ciência Ionosférica Durante o Eclipse
Operadores de rádio amadores que estudam a física espacial e a atmosfera superior investigaram a resposta da ionosfera ao eclipse solar anular de 2023 usando transmissões de ondas curtas.
Ionospheric Fireworks Illuminate Auroral Science
A sounding rocket experiment set off a spectacular nighttime light show over Scandinavia as it produced new insights into ionospheric behavior near an aurora.
