Solar eclipse and its effects on ionosphere.

      Аннотация: This work contributes immensely to current understanding of solar eclipses most especially total solar eclipses, it origin, and reveal a quite difference ionospheric behavior at different period of solar X-ray flare classes production during total eclipse in middle latitude ionosonde station situated along the path of totality of eclipse. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring Earth's view of the Sun. This configuration can only occur during a new moon, when the Sun and Moon are aligned as seen from the Earth. This phenomena and on ionosphere F2 are reveals.
