Abstract Under favorable conditions, the interaction between the interplanetary magnetic field (IMF) and Earth's magnetic field can result in a dayside aurora at magnetic latitudes above approximately 80°, referred to as the high latitude dayside Aurora (HiLDA). This term broadly includes several recently reported dayside auroras, such as space hurricanes and 15 MLT polar cap auroras (15MLT‐PCA). These phenomena are most prevalent in the summer, during a northward IMF, with component is positive in the northern hemisphere and negative in the southern hemisphere. This study examines the ionospheric electrodynamics of HiLDA events observed during the northern hemisphere summer, under two specific IMF conditions: a dominant positive IMF with a northward component and a dominant northward IMF with a near‐zero component. Using the local mapping of polar ionospheric electrodynamics (Lompe) data assimilation method, the following key findings are presented: (a) the HiLDA spot is positioned at the center of a clockwise lobe convection cell or within the clockwise convection region of the northward IMF (so‐called “NBZ”) current system. (b) The HiLDA spot is located not at the peak, but rather at the edge of an intensified upward field‐aligned current (FAC) associated with the convection vortex. (c) Significant Joule heating occurs in both IMF condition scenarios, with more pronounced heating observed under the dominated condition. These findings provide strong multi‐instrument support for a previously posed theory that the peak FAC is offset from the HiLDA spot and the center of the convection vortex.
