Multifrequency equatorial ionospheric scintillations in American and Indian zonesAmplitude scintillations of 40/41, 140 and 360 MHz transmissions recorded at Huancayo (phase I) and at Ootacamund (phase II) of the ATS-6 program are compared. The scintillations were found to be strongest between 20 and 24 hr LT with another peak around midday. The daytime scintillations do not show a significant seasonal variation at either of these stations. The nighttime scintillations were maximum during December solstices at Huancayo and during equinoxes at Ootacamund and suggested to be due to non-q type of sporadic E following the occurrence of counter-electrojet.
