From: Topside equatorial spread F-related field-aligned Poynting flux: observations and simulations

Parallel Poynting flux in the equatorial plane (above) and on an L-shell with an apex altitude of 520 km (below) for the equinox simulation depicted in Fig. 7 at 0100 UT. Red (blue) tones denote northward (southward) fluxes. The q-values shown correspond to magnetic latitudes between \(\pm 15^\circ\)
