Total electron content TEC observations were made at various midlatitude and high latitude stations using beacon satellite emissions from geostationary satellites. The Faraday rotation technique was utilized in making TEC Measurements during the periods near the minimum and maximum of the current solar cycle. Latitudinal, seasonal, and solar-cycle dependence of TEC were observed with seasonal effects being most consistent. Day-to-day variability of TEC, as expressed by the ratio of the monthly standard deviation of TEC to TEC was found to be approx. 25 for the daytime period irrespective of station position, season or solar cycle epoch.
