N2  - The changes in local time and altitude of the matrix elements of diffusion coefficients obtained for electron at the maximum electron density height (hmF2) in F2 region of the ionosphere are calculated on the equinox and solstice days for the Ankara / Turkey coordinates. Furthermore, the relationship between the most commonly used solar indices- F10.7 solar flux- and all elements of the diffusion coefficient matrix obtained at 240 km height is investigated. As a result of the examination, it is seen that element of Dxx of the coefficients matrix has the smallest and the element of Dzz has the greatest value. For the equinox months, it is seen that the difference between the maximum value and the minimum value in the daily variations of the diffusion coefficients is greater than in the solstices. A negative relationship at the same rate has nearly been determined between the F10.7 solar flux and all elements of the diffusion matrix.
