An embedded electron current layer observed at the edge of the plasma sheet in the Earth’s magnetotail
Published 2025-01-01“…The ions were demagnetized inside the electron current layer, but the electrons were still frozen in with the magnetic field line. Thus, this decoupling of ions and electrons gave rise to a strong Hall electric field, which could be the reason for the formation of the embedded thin current layer. …”

The Ionospheric Dynamics of the African Sector Responding to a Severe Geomagnetic Storm; the Storm of 3–5 November 2021
Published 2023-03-01“…The analysis of TIMED Global UltraViolet Imager images revealed storm time‐induced changes in thermospheric composition during the main phase which resulted in a differential ionospheric response with intense, moderate, and weak positive storm effects in northern, equatorial, and southern regions respectively. The horizontal magnetic field components show two signatures of prompt penetration electric field that suppressed the formation of the equatorial anomaly at SSC and enhanced positive storm effects in the equatorial region at the main phase, Therefore, the ionospheric response was due to the relative contributions of prompt penetration electric field effects and equatorward traveling disturbances which depended on storm onset time, past ionospheric state, and storm phase.…”
