Day into Night
Total Solar Eclipse passes over Cerro Tololo
17 Julio 2019
On 2 July 2019, a total solar eclipse passed over Chile and Argentina. Through a stroke of astronomical luck, the path of totality crossed directly over the National Science Foundation’s (NSF) Cerro Tololo Inter-American Observatory (CTIO) located in the foothills of the Andes, 7,241 feet (2200 meters) above sea level in the Coquimbo Region of northern Chile. During two minutes of totality, starting at 4:38 p.m. ET, the day turned into night when the moon completely covered the sun.
