Short summary
The solar flare effects on ionosphere at midlatitudes and low latitudes were investigated with the systematic analysis of ionospheric parameters derived from ionograms (total radio fade-out, fmin, dfmin: deviation from the reference days). The duration of the total fade-out varied with the solar zenith angle. Furthermore, a solar-zenith-angle-dependent enhancement of the fmin and dfmin parameters was detected but the observed values also depended on the flare intensity.
