In March 2019 a Space Weather Laboratory was deployed at Marambio base in the Antarctic Peninsula. The main instrument installed was a cosmic ray detector based on water Cherenkov radiation. This detector is the first permanent Antarctic node of LAGO Collaboration (Latin American Giant Observatory). LAGO Project is an extended Astroparticle Observatory and it is mainly oriented to basic research in three branches of Astroparticle physics: the Extreme Universe, Space Weather phenomena, and Atmospheric Radiation at ground level. LAGO Space Weather program is directed towards the study of how the variations of the flux of secondary cosmic rays at ground level are linked with the heliospheric and geomagnetic modulations. Observations made during 2019 and 2020 are presented here. We analyze the effect of barometric pressure and local temperature in the count rate. The corrected count rate observed with the water Cherenkov detector is compared with observations of Oulu neutron monitor which has similar rigidity cut-off than the Marambio site.
