The ionospheric total electron contents(TEC)during the total eclipseof October 24,1995 were observed by means of the Global Positioning System(GPS)receivers located at Wuchang and Guangzhou.The observationsshowed that there were obvious effects of the eclipse on the ionosphere.The eclipse gave rise to decreases in the TEC in comparison with an establishedTEC reference level,refered to as the negative deviations of the TEC.The deeper the obscuration degree was,the larger was the negative deviation.Furthermore,the restoration of the negative deviations was delayedby about 2 hours after the last contact of the eclipse.
