Abstract: The Faraday fading records of 40 MHz transmissions from the beacon satellite BE-C recorded at Kurukshetra (lat. 29'9°N; long. 76'8°E) during Oct. 1970-May 1972 have been utilized for the study of : (i) the latitudinal variation of occurrence of scintillations; (ii) the correlation of scintillation index (SI) with foF2 and total electron content (TEC); (iii) the effect of solar activity on scintillations and (iv) the correlation of SI with spread-F. The percentage occurrence of scintillations was observed to be higher towards north than towards south of Kurukshetra with a minimum occurrence between 27° and 28°N sub-ionospheric latitude. The SI bears negative association with foF2, TEC and solar activity, and it is found to be positively correlated with spread-F index.
