The Large Latin American Millimeter Array (LLAMA) is a single-dish 12 m Nasmyth optics antenna which is under construction in the Puna de Atacama desert in the Province of Salta, Argentina, next to the Qubic experiment.

LLAMA is a joint project between Argentinian and Brazilian Astronomers to build and operate a radio telescope at submillimeter wavelengths, that can work in stand alone mode or join a Very Long Baseline Interferometry (VLBI) network.

The history of the instrument can be traced back to 2007, during the XII Latin American Regional IAU Meeting (LARIM)[1] held in Isla de Margarita (Venezuela).

The formal presentation before the Argentinian Science Ministry (MinCyT) was in 2010, while a meeting held at the offices of FAPESP in August 2011 was the kickoff in Brazil.

The final agreement, between MinCyT, FAPESP and Universidade de São Paulo (USP), was signed in June 2014, and on July 9, it was formally presented to the public.

[9] The observatory acronym comes from the Quechuan word llama that designates the South American camelid that lives in the region where the telescope is being installed.

[11][12] Therefore, LLAMA observations will bring new information about the structure of the lower Solar Atmosphere, the active and quiescent filaments and the dynamics of the chromosphere and its magnetic field.

For example, in a joint observation between LLAMA and some of the ALMA antennas, a spatial resolution of 0.001" would be achieved for λ ≈ 1 mm, corresponding to a distance of 700 m on the solar surface.
