South American auroral reports during the Carrington storm
Earth, Planets and Space, 2020 The importance of the investigation of magnetic superstorms is not limited to academic interest, because these superstorms can cause catastrophic impact on the modern civilisation due to our increasing dependency on technological infrastructure.

Journal of Geophysical Research: Space Physics, 2001 Jupiter's aurora shows, among other features, a persistent, continuous oval of luminosity that encircles each magnetic pole and maps along magnetic field lines to the middle magnetosphere (r ≈ 30 Rj). This auroral oval is interpreted here as the ionospheric footprint of the upward Birkeland (magnetic field aligned) current that enforces partial ...

Astrid-2 and ground-based observations of the auroral bulge in the middle of the nightside convection throat [PDF]
Annales Geophysicae, 2001 Results concerning the electrodynamics of the nightside auroral bulge are presented based on simultaneous satellite and ground-based observations. The satellite data include Astrid-2 measurements of electric fields, currents and particles from a ...

Climatology of GPS phase scintillation and HF radar backscatter for the high-latitude ionosphere under solar minimum conditions [PDF]
Annales Geophysicae, 2011 Maps of GPS phase scintillation at high latitudes have been constructed after the first two years of operation of the Canadian High Arctic Ionospheric Network (CHAIN) during the 2008–2009 solar minimum.

An empirical model of the auroral oval derived from CHAMP field-aligned current signatures – Part 2 [PDF]
Annales Geophysicae, 2014 In this paper we introduce a new model for the location of the auroral oval. The auroral boundaries are derived from small- and medium-scale field-aligned current (FAC) based on the high-resolution CHAMP (CHAllenging Minisatellite Payload) magnetic ...

Investigations of the auroral luminosity distribution and the dynamics of discrete auroral forms in a historical retrospective [PDF]
History of Geo- and Space Sciences, 2014 Research results about planetary-scale auroral distributions are presented in a historical retrospective, beginning with the first "maps of isochasms" – lines of equal visibility of auroras in the firmament (Fig.

Observed effects of a geomagnetic storm on an RTK positioning network at high latitudes
Journal of Space Weather and Space Climate, 2012 At high latitudes, above 60° N, in the vicinity of the auroral oval, the ionosphere frequently experiences disturbed conditions that impact GNSS-based services.

Stationary magnetospheric convection on November 24, 1981. 1. A case study of "pressure gradient/minimum-B" auroral arc generation [PDF]
Annales Geophysicae, 1999 We present two case studies in the night and evening sides of the auroral oval, based on plasma and field measurements made at low altitudes by the AUREOL-3 satellite, during a long period of stationary magnetospheric convection (SMC) on November 24 ...

Relative positions of the polar boundary of the outer electron radiation belt and the equatorial boundary of the auroral oval [PDF]
Annales Geophysicae, 2018 Finding the position of the polar boundary of the outer electron radiation belt, relative to the position of the auroral oval, is a long-standing problem.
