Energetic electrons are accelerated directly by magnetic reconnections and can act as tracers of large-scale magnetic field conditions.

Deciphering Electron Signatures in Earth’s Magnetic Tail
A new analysis of spacecraft data collected near the tip of Earth’s magnetotail sheds light on how geomagnetic activity affects the motion of electrons in this region.
Can Moderate Space Weather Have Major Impacts?
Pipeline corrosion is an example of why we need better awareness of how long-term exposure to moderate space weather may have significant economic impact by slowly degrading vulnerable systems.
Measuring the Magnetic Reconnection Rate in the Magnetotail
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.
New Explanation for “Meandering” Electrons Orbiting Earth
A new study proposes a simpler theory to explain a class of electrons zipping around Earth, propelled by magnetic explosions.
