Global characteristics of auroral Hall currents derived from the Swarm constellation: dependences on season and IMF orientation [PDF]
Annales Geophysicae, 2017 On the basis of field-aligned currents (FACs) and Hall currents derived from high-resolution magnetic field data of the Swarm constellation, the average characteristics of these two current systems in the auroral regions are comprehensively ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We investigate Ionosphere‐Thermosphere (IT) responses to the March 2023 geomagnetic storm using GOLD and PFISR observations, along with TIEGCM simulations driven by data‐assimilated aurora and electric fields. A Lattice Kriging approach is implemented to assimilate auroral electron flux and characteristic energy from ground‐based (THEMIS/ASIs)

Accurate Ionospheric TEC Prediction With a Causal Attention Network at Northern EIA Crests
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract As the Sun approaches the peak of its 25th activity cycle, precise ionospheric forecasting has become increasingly challenging. Low‐latitude regions have emerged as a persistent bottleneck for space weather operations. Extensive evidence reveals that existing AI models exhibit significant performance degradation in these regions, demonstrating

Equatorial Electrojet Current System [PDF]
, 1972 12-18Equatorial electrojet is a day-time enhancement of the normal Sq field in a narrow band of 4-5ᵒ width along the magnetic equator. Its width, intensity, seasonal and sunspot cycle variations over different regions of the earth have been discussed ...

Austral electrojet indices derived for the great storm of March 1989 1177
Annals of Geophysics, 1996 Available magnetic records from eight stations in the Antarctica, for the March 1989 geomagnetic storm, are used to construct the southern hemisphere auroral indices, analogous to the boreal ones.

An intense SFE and SSC event in geomagnetic H, Y and Z fields at the Indian chain of observatories [PDF]
Annales Geophysicae, 1997 Changes in the three components of geomagnetic field are reported at the chain of ten geomagnetic observatories in India during an intense solar crochet that occurred at 1311 h 75° EMT on 15 June 1991 and the subsequent sudden commencement (SSC) of ...
