FOF2 FREQUENCY BANDS IN EL CERRILLO, MEXICO DURING MAGNETICALLY QUIET CONDITIONS
This work describes the foF2 frequency bands (maximum-noon, minimum-midnight bands) and their main characteristics during magnetically quiet conditions and extreme conditions of solar activity. We have observed that there is a seasonal variation and parallel behavior between frequencies during High Solar Activity and Low Solar Activity. During High Solar Activity we can observe the seasonal anomaly and symmetry between both frequency bands.
