Resumen:
Using measurements of the critical frequency of F2 region (foF2) the validity of the International Reference Ionosphere model to predict the time of minimum ionization is checked. Data obtained at stations placed in the American sector, Japan, Philippines and Australia corresponding to different months and solar activity conditions are considered. The CCIR and URSI options are used to model calculations.The results show that, for high solar activity, there are good predictions for about 40% of the considered cases. For low solar activity there are good predictions for about 25 % and 30% of the considered cases in the American sector and the other network, respectively. For the other cases, in general, the model predicts the minimum at times earlier than that oberved in the data.
