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.
Solar Eclipses May Initiate Disturbances in Geospace
The statistical evidence from 21 years of data suggests that a solar eclipse may trigger a geomagnetic substorm, which is a disturbance in the Earth’s magnetosphere and ionosphere.
