                         variation during nighttime, based on data collected by 
                         ground-based Global Navigation Satellite System (GNSS) networks 
                         over the Latin America region. This qualitative and quantitative 
                         nighttime analysis of the ionospheric TEC is focused on : (1) the 
                         response of TEC to the solar flux at 21:00, 00:00 and 03:00 local 
                         time (LT); (2) the seasonal variation of TEC in different 
                         latitudes during nighttime; and (3) the North-South density 
                         asymmetry of TEC. The response to the solar flux is based on TEC 
                         variations during two periods of different solar activity 
                         conditions: 2011 (ascending phase) and 2014 (maximum). Among the 
                         results, we highlight a strong latitudinal dependence of nighttime 
                         TEC variation, an absence of semiannual anomaly for GNSS stations 
                         at mid latitudes. The Midlatitude Summer Nighttime Anomaly (MSNA) 
                         was also identified in the Southern hemisphere during January and 
                         December.",
