             abstract = "South America is one of the most active thunderstorm regions of 
                         the world. About 20 years ago, it was discovered that thunderstorm 
                         electrical activity, in the form of lightning discharges, can 
                         excite Transient Luminous Events TLEs in the upper atmosphere 
                         directly above it. More recently, measurements of High Energy 
                         Emissions from Thunderstorms HEET from space revealed that they 
                         also produce high energy emissions. Up to date, six different 
                         field campaigns, between 2002 and 2012 have been successfully 
                         performed in Brazil to make TLE observations. More than 700 
                         events, mainly sprites, have been recorded over thunderstorms in 
                         different places in South America during these campaigns. Given 
                         the high thunderstorm electrical activity in our region, extremely 
                         high TLE occurrence rates as well as intense emissions of TGFs, 
                         electron and neutron beams, i.e. HEET in general, are expected. 
                         Both classes of phenomena are collectively called Effects of 
                         Electrical Activity Related to Convective System FARIES, or 
                         Efeitos da Atividade El{\'e}trica de Sistemas Convectivos FADAS, 
                         in Portuguese. The FAIRIES/FADAS are the object of research of the 
                         Transient Luminous Event and Thunderstorm High Energy Emission 
                         Collaborative Network in Latin America LEONA, whose core was 
                         established in Brazil in 2014 with 4 ground stations. The TLE 
                         stations are operated remotely via internet, by users logged in 
                         LEONA website, and the HEET station is automatically operated. Now 
                         we are planning to expand LEONA to have 12 TLE ground stations, 2 
                         fixed and 1 mobile HEET stations. The expanded version of LEONA 
                         will cover the Central Region of South America, including 
                         Southeastern and Southern Brazil, Northern Argentina, Paraguay and 
                         Uruguay, which compose the most electrically active Region of 
                         South America. Due to the South Atlantic Magnetic Anomaly SAMA, 
                         covering most of its territory, scientific satellites routinely 
                         turn off their equipment while flying over South America, 
                         therefore a ground network like LEONA is the only way to make 
                         consistent long term measurements of TLEs and HEET in this 
                         important region of the world. In this paper we will present in 
                         detail the current status of LEONA network and we will present the 
                         first results of our analysis of the effects of FARIES detected 
                         over Brazil in the Ionosphere.",
