Outside the path of totality, the eclipse is partial with significant coverage in large cities such as Santiago, Chile (93%); Montevideo, Uruguay (94%); La Paz, Bolivia (63%); and Lima, Peru (54%). During the partial phase of the eclipse, the sun looks like a crescent, and it casts crescent-shaped shadows on the ground. South Americans should look for them underneath the canopies of leafy trees. Using safe eclipse glasses, it is possible to view the crescent sun directly.
The sun and Moon align for an eclipse once or twice every year. Aligning directly over a major observatory, however, is very rare. This video shows what the eclipse will look like over La Silla:
