Abstract: 
Variations of ion concentration caused by sunrise are analysed on the basis of satellite observations of low-latitude F2 region of the ionosphere. The photoionization influence on ion composition is caused both by direct increase of plasma density and by the variation of chemical reaction rates. A simplified model is constructed in the photochemical approximation. The model describes adequately detected changes of density of various ion components after the beginning of ionization.
Keywords: F2 region, ion concentration, ionosphere
