A correlation between AKR-like emissions and field-aligned currents

In this study, we searched for and analysed cases of co-occurrence of the growth of the density of field-aligned currents (FAC) and AKR-like emissions. Several cases have been found in which the occurrence of AKR-like emission corresponds to an increase in FAC density. We can infer that FACs accompany the AKR-like emissions, but not necessarily the presence of these currents does imply the existence of these emissions in the entire latitudinal/longitudinal range for which FACs are observed. There would probably be more such coincidences if there were more close flybys/orbit intersections of the Swarm and Vernov satellites. Observations fall between August and December of 2014 (mid-24th solar cycle).
