The analysis shows that the ionospheric TEC possesses close connection with daily Zurich relative sunspot numbers Rz and solar fluxes at 2800 MHz S, which generally appears a positive correlation. The response of TEC to S is clearer than that to Rz. At the peak of the sunspot cycle the effect of solar activily is severe. The geomagnetic planetary three-hour index Kp, its first-half day sum ∑K p1 , se-cond-half day sum ∑K p2 , whole day sum ∑K p ,as well as mixed whole day sum ∑’K p , are sujtable indices for investigating the response of daytime and （or） nighttime TEC to magnetic, disturbance. Under the condition of the Western Europe midlatitude during solar maximum the reaction of midnight and midday integrated concentration to ∑K p and D’K p presents mainly an anti-correlation, Which is especially typical during summer arid may be called the summer ano-maly of the gcomagneto-ionospheric disturbance. 1984-04-01 2021-04-01 4
