Abstract: This paper presents the simulated results of the ionospheric responses to a solar eclipse occurred on October 24, 1995 using a 2D low latitude ionospheric theoretical model. The variations of ion photoionization productions, E×B vertical drifts and electron temperatures induced by the eclipse are considered in the modeling calculations. Results show that during the eclipse, optical eclipse effects are quite clear at the low altitudes, while the responses are smaller, more delayed and longer lasting at the high altitudes. The effects of the depression of electron temperatures induced by the eclipse on the low latitude Flayer are smaller comparing with those caused by variations of EUV fluxes and vertical drifts, which are important for the ionospheric effects of this eclipse.
