Dawn-dusk (y) component of the interplanetary magnetic field and the local time of the harang discontinuity
Read more of: Dawn-dusk (y) component of the interplanetary magnetic field and the local time of the harang discontinuityWe describe a simple method for determining the time at which the meridian of a sub-auroral magnetic observatory crosses that of the Harang discontinuity—the separation of the eastward and westward […]

Spread-F ionospheric irregularities and their relationship to stable auroral red arcs at magnetic mid-latitudes
Read more of: Spread-F ionospheric irregularities and their relationship to stable auroral red arcs at magnetic mid-latitudesThe signature of the stable auroral red arc (SAR arc) as it appears on ionograms is described. The key features are a very significant increase in the amount of spread-F […]
