The LAGO (LAGO: Latin American Giant Observatory) project is acollaborative network formedby elevencountries (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guatemala,Mexico, Peru,Spain, and Venezuela). The network of WCDs has nodes at sites withdifferent rigidity cut-offs anddifferent altitudes. One of the aims of LAGO is to study the flux of thesecondary particles at groundlevel, and to link them with the associated primary fluxes to betterunderstand the modulationof CRs in the helisphere. Another main aim is to monitor this flux toprovide operative SpaceWeather information. We present an update of the state of the art of theLAGO Antarctic node, tobe deployed in the Argentine Marambio base, in the Antarctic peninsula. Inparticular we presentstudies of the atmosphere in Marambio and the effects of the geomagneticfield on the arrival ofcosmic rays to this antarctic site. This node will have the minimumrigidity cut-off (Rc ̃ 2 GV) ofthe collaboration, and will be the only LAGO node that will be able toobserve GLEs. We presentthe LAGO antarctic campaign of 2017-2018 in Marambio, where ameteorological station will beinstalled, a thermal control system will be tested, and several tests oftelemetry from Antarctic toBuenos Aireswill be done
