ResumoThe minimum period of the solar cycle 23/24 was abnormally deep and extended have been inspiring several studies on solar physics, on ionosphere/thermosphere system and on climate. In this work we present some results for this period extracted from ionospheric data over Brazilian region at two equatorial sites, Sao Luis (44.2° W, 2.33° S, dip angle: ?6.9°) and Fortaleza (38.45°W, 3.9° S, dip angle: ?16°) and at the low latitude station Cachoeira Paulista, CP (22.4° S, 45° W, dip angle: -37°). It was observed that the plasma densities during the last solar minimum were lower than that observed in the previous period in 1996, but only for some periods. An abnormal occurrence rate of spread-F/plasma irregularities over CP was observed during June solstice of solar minimum. Besides, the ionograms acquired in all stations revealed distinct patterns of spread-F associated with midnight/post-midnight irregularities. Over the equatorial region, it was observed significant decreases in the plasma densities during nighttime periods with no-echoes in the ionograms lasting for several hours. Afterwards, the same distinct spread-F patterns were observed during the ascending phase (2011) of the current solar cycle over the equatorial region, both with Digisondes and coherent backscatter radar. It will be discussed the nature of the observed plasma irregularities and of the ionosphere behavior under the influence of the solar minimum activity.
