What is Argentina's full flag with the sun called in Spanish?

Argentina’s full flag with the Sun of May is called the Bandera Oficial de Ceremonia in Spanish. It is the official ceremonial flag, while the version without the sun is known as the Bandera de Ornato, or ornamental flag.

Both versions are legally regarded as Argentina’s national flag, but they have different formal uses. The ceremonial version carries a golden sun with a human face in the center of the white stripe. The ornamental version has the same light-blue and white triband without that emblem.

The Sun of May was added to Argentina’s flag in 1818. Its design was based on the sun appearing on the first coin of the United Provinces of the Río de la Plata, approved in 1813. The emblem has 32 alternating rays: 16 straight and 16 wavy.

In formal display, the ornamental flag must be hoisted below the Official Ceremonial Flag. A common mistake is to treat the sun-bearing design as the only national flag; Argentina officially recognizes both forms, with the ceremonial version reserved for more formal contexts.
