Sub-auroral Ionosphere (latitudes below auroral ovals). Stable auroral red (SAR) arcs (magnetic activity effects that transfer magnetospheric ring current energy into the I-T system) 1. Equatorial and low latitude Ionosphere (from magnetic equator to the crests of the Appleton Anomaly).

    Washington, DC: The National Academies Press. doi: / (HF) ionospheric heating experiments at high latitudes, combined with incoherent and coherent radar measurements of the ionospheric dynamics and with multi-satellite observations of the global magnetosphere configuration during both quiet and extreme solar-wind driving. Auroral emissions can be seen extending to high latitudes on the nightside. Also evident are the terminator (the boundary between the dayside and the nightside) and, at the right of the image, bright ultraviolet dayglow emissions from the sunlit hemisphere. Phenomena associated with plasma-neutral interactions and radiation-plasma.

    These proceedings are based on the invited talks and selected research reports presented at the NATO Advanced Study Institute (ASI) on "POLAR CAP BOUNDARY PHENOMENA" held at Longyearbyen, Svalbard, June 4 - 13, The role of the polar cap and its boundary is very substantial in. But in the aurora the illumination can be miles ( kilometers) high, stretch for thousands of miles, and be linked to a magnetospheric power generator churning out three million megawatts.

In a quiet auroral arc a disturbance may occur e.g. due to Kelvin-Helmholz instability associated with a convection shear along the arc. Also, a vortex of plasma flow can arise due to some kind of the Rayleigh-Taylor instability [6].Figure 1 presents a sketch of wave-like distortions in the field-aligned currents and plasma flows connected to an auroral arc.

High solar wind Since the auroral. An aurora (plural: auroras or aurorae), sometimes referred to as polar lights, northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic).

Auroras are the result of disturbances in the magnetosphere caused by solar wind. Volume 7, IssueOctober ISSN: (Print) Auroral and associated magnetospheric phenomena at very high latitudes.

Aurora, luminous phenomenon of Earth’s upper atmosphere that occurs primarily in high latitudes of both hemispheres; auroras in the Northern Hemisphere are called aurora borealis, aurora polaris, or northern lights, and in the Southern Hemisphere aurora australis, or southern lights.

Accurate mapping of the auroral oval into the equatorial plane is critical for the analysis of aurora and substorm dynamics. Comparison of ion pressure values measured at low altitudes by Defense Meteorological Satellite Program (DMSP) satellites during their crossings of the auroral oval, with plasma pressure values obtained at the equatorial plane from Time History of Events and Macroscale Cited by: The connection between auroral activation and magnetic impulse events, (MIE) on the nightside is the issue of this study.

MIE can be seen during the growth phase and onset of a substorm in association with field-aligned currents (FACs) connecting the auroral ionosphere and plasma : M. Danielides, S. Shalimov. Auroral activity occurred in the late afternoon sector ({approximately} 16 MLT) in the northern hemisphere during the passage at Earth of an interplanetary magnetic cloud on Janu The auroral activity consisted of a very dynamic display which was preceded and followed by quiet auroral displays.

Many of the most basic aspects of the aurora remain unexplained.
