| Sumario: | The project involving a new laboratory of Space Weather at the Argentine Marambio base in Antarctica, required the assembly of an automatic thermal control for the interior of its main room, a meteorological station, a magnetometer, and a cosmic ray detector. This Antarctic laboratory is part of an interdisciplinary project involving different institutions, among which are mainly the Instituto de Astronomía y Física del Espacio, IAFE (CONICET-UBA), the Instituto Antártico Argentino (IAA-DNA) and the Departamento de Ciencias de la Atmósfera y los Océanos (DCAO) of the Facultad de Ciencias Exactas y Naturales (FCEyN) of the Universidad de Buenos Aires (UBA). Knowing the variability of cosmic rays fluxes at ground level is crucial to characterize the conditions of Space Weather. Severe Space Weather events can affect modern technologies, such as geo-positioning systems, radio-frequency communications, and damage satellites, among others. Understanding the origin and transport of cosmic rays requires interdisciplinary knowledge in physics, in astronomy, in space sciences and in meteorology, since these energetic particles of galactic origin interact with the interplanetary plasma and magnetic field, the geomagnetic field and with the particles of the atmosphere before reaching the surface of our planet. Part of the instrumentation contained in the laboratory include a cosmic rays detector, based in Water Cherenkov radiation, called Neurus. This astroparticle detector is also part of the LAGO Observatory (Latin American Giant Observatory) constituting the southernmost detector of them, in an uninterrupted operation since March 2019 when it started its observations. LAGO is a spin-off of the Pierre Auger observatory, with a concept of developing cosmic ray detectors by Cherenkov effect in water of low cost and reduced size, consisting of decentralized nodes that span from Mexico to Antarctica. The particle detector Neurus was constructed and developed with specific antarctic characteristics in the space laboratory of IAFE by the LAMP (Laboratorio Argentino de Meteorología del esPacio) team, and it allows for monitoring in real time the flux of cosmic rays that reaches the surface of the Earth, at high latitudes in the southern hemisphere. |
