With the development of satellite technology, low-orbit satellites equipped with high-resolution magnetometers have become an important tool for measuring the Earth's magnetic field, which provides continuous observations around the world regardless

Abstract Theoretical studies indicate that electric potential saturation in a polar cap ionosphere is regulated by the limited reconnection rate at the magnetopause associated with field‐aligned currents (FACs), predicting the possible saturation o

Abstract The magnetopause is the boundary between the Earth's magnetosphere and the solar wind. Magnetosheath high‐speed jets can impact the magnetopause, causing local indentation and subsequently rebound. However, the comprehensive response of th

Abstract The morphology and motion of auroras have been widely studied due to their indications on magnetospheric processes. Here, we report a new kind of “auroral curls,” which have wavelengths in the mesoscale (∼100 km) and propagate azimutha

Field aligned currents (FACs), also known as Birkland current, are flowing along the magnetic field line between the ionosphere and magnetosphere. They play an essential role in transferring mass, energy, and momentum from the magnetosphere to the io

To understand the similarities and differences between the duskside mesoscale quasistatic field-aligned currents (FACs) and the dawnside mesoscale FACs, we examined the magnetic field data obtained through the constellation measurements of Swarm sate

Abstract The preliminary impulse of the sudden commencement is simply explained by the generation of the compressional wave due to sudden compression of the dayside magnetopause and mode conversion from the compressional wave to the Alfvén wave in t

Abstract Using a conjunction of Cluster in the mid‐altitude dayside magnetosphere and Swarm in the low‐altitude ionosphere, we show, by employing multi‐spacecraft analysis, that matched, strong magnetic perturbations and the corresponding mesos
