Mendoza: Andean Alpenglow Over the Vineyard City

Hora dourada, hora azul e crepúsculo em Mendoza. Dados astronômicos NASA JPL DE441.

Conselho fotográfico

Cerro de la Gloria summit at golden hour: face northwest for the Aconcagua silhouette above the Andean foothills. Arrive 30 minutes before sunset to catch the pre-alpenglow sequence — as the sun drops behind lower ridges, watch the light progressively withdraw from the range before the alpenglow fires on Aconcagua.

Mendoza sits at 32.9°S, 750 m elevation, at the foot of the Andes in western Argentina. Aconcagua (6,962 m, highest peak in the Americas) is visible to the west-northwest on clear days. Golden hour lasts roughly 34 minutes. The Andes rise so dramatically that sunset behind the range happens 15–20 minutes before horizon sunset — immediately after the sun drops behind the peaks, the sky transitions from gold to deep magenta in a rapid alpenglow sequence. Cerro de la Gloria (950 m, 3 km from the city centre in Parque General San Martín) faces west over the city and the Andean foothills. The vineyard areas (Chacras de Coria, Luján de Cuyo, Maipú) 10–25 km south and west have east-west vine rows that channel the sun at golden hour from either end.
