Ionospheric profiles forecasts by the IRI ionospheric model for the conditions prevailing during the observation. Left panel: Electron density. Middle panel: Ion temperature (red line) and electron temperature (green line). Right panel: ion rates. Red line: O⁺; Light blue: NO⁺; dark blue: $O_{2}^{+}$ ${\mathrm{O}}_2^{+}$ . The other ions (N⁺ and H⁺) are shown but negligible.
