Since 1957 to 1987 ionospheric measurements were obtained with the analogue ionosonde of the Ionospheric Station of National University of Tucumán, placed near the southern crest of the equatorial anomaly. That ionosonde was out of order in 1987. In 2007 an Advanced Ionospheric Sounder (AIS), built at the Istituto Nazionale di Geofisica e Vulcanologia, Rome, was installed at the Upper Atmosphere and Radiopropagation Research Center (Centro de Investigación de Atmósfera Superior y Radiopropagación ? CIASUR) of the Tucumán Regional Faculty of the National Technological University. The first results obtained with AIS measurements in previous works are mentioned. Comparisons between analogue and AIS ionosondes measurements and IRI predictions are shown
