This paper present the analysis of the F region variability of the ionosphere during the Low solar activity period year
2009 for three stations of low, mid and high latitude Chongqing (29.43ᵒN,106.92ᵒE), Beijing (39.91ᵒN,116.41ᵒE) and Sodankyla
(67.40ᵒN,26.59ᵒE) respectively. In the study we discussed the diurnal, seasonal, and monthly variability of foF2 at all the above
mentioned stations. We observed that the peak values of foF2 are comparatively much higher at high latitude (25%) than at mid
latitude (7%) and low latitude (9%). It is also observed that during the month of November, high and mid latitude shows the
maximum variation of foF2 while low latitude location Chongqing shows it maximum in the month of March. Which clearly
indicates that the presence of winter anomaly at high and mid latitude whereas low latitude maximum in summer month .
