Description

The space weather program of the LAGO project aims to study the galactic cosmic ray modulation estimated from the measurement of secondary cosmic ray flux in the network of detectors of the project. The experiment consists of several water Cherenkov tanks located at different altitudes, ranging from sea level (Lima) up to 5000 meters above sea level (Chacaltaya), and latitudes, which span most of Latin America from 18◦59′N (Sierra Negra) to 41◦09 ′ S (Bariloche). The operation of a detector in the Antarctica is also being considered. In order to monitor the flow of secondary cosmic rays, a dedicated web monitor has been developed. The monitor automatically calibrates the flow of charge deposited in the detectors every hour, correcting for the long term loss of sensitivity as well as for pressure. The cosmic ray flux, measured by the detectors in bands dominated by different types of particles, is shown hourly. We show details of the automatic semi-analytic calibration method that was developed and the web monitor operation.
