Routine SuperDARN observations of the ionospheric plasma convection and field-aligned currents (FACs) in the high-latitude ionosphere are used to study current systems established at small interplanetary magnetic field (IMF) B z and B y , By statistical averaging of available data sets we show that under this IMF condition the ionospheric convection pattern consists of two (evening and morning) convection cells that are similar in shape. The flow intensity inside the central polar cap is… CONTINUE READING
