TL;DR: In this article, the authors investigated whether one or a few coupling functions can represent best the interaction between the solar wind and the magnetosphere over a wide variety of magnetospheric activity.

TL;DR: In this article, the authors used magnetometer chains collaborating with SuperMAG to derive SME, a generalization of the auroral electrojet indices calculated from 100 or more sites instead of the 12 used in the official AU(12) − AL(12), and investigated how these various indices relate to nightside auroral power by using both particle (DMSP) and image (Polar Ultraviolet Imager (UVI)) data.

TL;DR: In this paper, the authors investigated the distinction between the low-altitude cusp and the cleft (with the latter identified as the ionospheric signature of low-latitude boundary layer (LLBL)) on both a statistical and a case study basis.

TL;DR: In this article, a complementary approach is tried: regions are identified based on the plasma characteristics as observed by low-altitude satellites using an automated identification scheme applied to approximately 60,000 individual satellite passes through the dayside oval, probability maps are computed for observing various types of plasma precipitating into the ionosphere.

TL;DR: In this article, the authors developed an auroral precipitation model which separately categorizes the discrete aurora and both the electron and ion diffuse aurora, based on functional fits to the solar wind coupling function which best predicts auroral power.
