An international armada of orbiting satellites and ground VLF network join forces to form a “magnetosphere-ionosphere observatory” to size up electromagnetic ion cyclotron waves in the magnetosphere.
Both simulations and observations are used to measure the magnetic reconnection rate in the Earth’s magnetotail, suggesting that the rate is correlated with the intensity of a magnetic substorm.
Energetic particle data from the Global Positioning System constellation opens avenues for new research.
In a new conference and collection of papers, international space physicists narrow down the enigmas that puzzle magnetospheric science.
When solar storms pounded Earth during Halloween in 2003, scientists were eager to measure their effects. But new research shows one satellite was seeing "ghost" particles that probably weren't real.
