Total Electron Content (TEC) was determined between October, 1975 and August, 1976 from measurements of the Faraday rotation of a plane polarized wave transmitted at 140 MHz from the geostationary satellite ATS 6, located at approximately 35 deg E over the equator. The computed results are presented as diurnal variations for single days and monthly means. Maximum daytime TEC values were observed in April (about 20 x 10/sup 16/ el/sq m) and minimum in January (about 9 x 10/sup 16/ el/sq m); maximum night-time values were observed in January and February (about 3 x 10/sup 16/ el/sq m). The response of TEC to the high magnetic activity associated with substorms was found to depend greatly on the time of day when the storm occurred.
