The antarctic Space Weather Laboratory was deployed by the LAMP group (Laboratorio Argentino de Meteorologíadel esPacio) at the Argentinian Marambio base in the Antarctic Peninsula.The main instrument installed was a cosmic ray detector based on water Cherenkov radiation, and it started tooperate in March, 2019. Since then, it has been continuously measuring the flux of secondary cosmic rays (SCR).Two main aims of this high latitude detector are: (1) making progress of fundamental science and (2) space weathermonitoring. This detector is a node of the LAGO Collaboration (Latin American Giant Observatory).In this work, we will show the calibrated SCR count-rate for the first year of its operation. Also, we will discuss abouta seasonal modulation which was found in those measurements during this period
