After 967 years, on 12/14/2020 a total solar eclipse occurred in Junín de los Andes. The research questions were: What changes occur on the earth's surface during a total solar eclipse in luminosity, temperature, atmospheric pressure, winds, and cosmic radiation? How much does cloud cover influence? In the city, records of luminosity, air, surface and ground temperatures were taken. GLOBE-Observer was used for air and cloud temperatures; the Cosmic-Watch detector for cosmic ray flux. Atmospheric pressure and wind speed were obtained from a nearby weather station. For the eclipse path, records were obtained from nearby weather stations and GOES-16 images of temperature and cloud cover. In the city the luminosity and surface temperature decreased during the totality, the air temperature decreased afterwards. Cloud cover was low. The atmospheric pressure decreased and the wind speed increased, although it cannot be attributed solely to the eclipse. The other variables did not register changes. The eclipse path had cloud cover and the temperature dropped after totality. During the totality there were changes in the earth's surface, in luminosity, air and surface temperature. It is recommended in the future to carry out citizen participation campaigns to study in detail the meteorology of eclipses.
