In this paper, the changes in the ionosphere over Turkey due to two solar eclipses are reported. TEC on the eclipse day (26 April 1976) and the intensity of an HF radio wave during its propagation over 567 km between Ankara and Elazig on the eclipse day (11 August 1999) exhibited a very marked decrease.
