Is the poleward edge of the trough a sensitive indicator of geospace interactions?
Read more of: Is the poleward edge of the trough a sensitive indicator of geospace interactions?The poleward edge of the main ionospheric trough can often be regarded as the ionospheric signature of the equatorward boundary of the plasma sheet. We use Advanced Ionospheric Sounder observations […]

The effect of geomagnetic activity on north polar currents in winter
Read more of: The effect of geomagnetic activity on north polar currents in winterAverage north polar currents for the winter season have been derived from geomagnetic hourly means at six levels of geomagnetic activity. The twin-vortex pattern, normally associated with more disturbed conditions, […]
