The longitudinal and transverse correlation functions for the fluctuations in the angle of arrival on the entrance pupil of a solar telescope have been estimated. The results are found to be consistent with the inertial model of turbulence. Values of the integral ∫ <i>C</i><sub><i>N</i></sub><sup>2</sup>dh of the structure constant over the lower atmospheric layers and of Fried’s seeing parameter <i>r</i><sub>0</sub> are deduced. They are found to be consistent with other independent estimations made with the same telescope.
