Abstract: Scintillation study carried out at Varanasi (geomag. lat., 14°55 'N) using geostationary satellite FLEETSAT signals at 244.168 MHz is reported. Conventional recording system has been used. The time of peak occurrence is found to vary from month to month and is predominant in the pre-midnight period. The seasonal dependence of nighttime scintillation variation shows a maximum occurrence of 20% for equinox at around 2100-2200 hrs IST. The effect of magnetic activity on scintillation occurrence was examined and it is found that there was no scintillation at all in summer on quiet days in the pre-midnight period. The computed scintillation index also exhibits nighttime variation. These features are compared with available results at low and mid latitude stations.
