Almost 40 years ago the concept of the substorm current wedge was developed to explain
the magnetic signatures observed on the ground and in geosynchronous orbit during …

Meso-scale auroral forms, such as poleward boundary intensifications, streamers, omega
bands, beads and giant undulations, are manifestations of dynamic processes in the …

The present 15th volume of the ISSI Space Science Series is devoted to Auroral Plasma
Physics. The aurora is arguably the most intriguing phenomenon in space plasma physics …

Earthward flow bursts associated with small auroral expansions, including pseudobreakups,
and auroral streamers are studied by using Geotail plasma and magnetic field data and …

We use observations from five magnetospheric spacecraft in a fortuitous constellation to
show that narrow transient plasma flow jets of considerable length formed in the tail can …

During the long-duration steady convection activity on 11 December 1998, the development
of a few dozen auroral streamers was monitored by Polar UVI instrument in the dark …

Forecasting geomagnetically induced currents (GICs) remains a difficult challenge, and
open questions hindering our understanding include when and where GICs become large …

Nightside auroral zone localized flow channels, typically associated with auroral poleward
boundary intensifications and streamers, are an important component of high‐latitude …

The substorm current wedge (SCW) is a fundamental component of geomagnetic substorms.
Models tend to describe the SCW as a simple line current flowing into the ionosphere toward …

The magnetosphere‐ionosphere coupling between the high‐speed earthward flows and the
north‐south oriented streamers in the ionosphere has been discussed for decades, but to …
