AbstractAn East–West one-dimensional radio interferometer array consisting of 5 parabolic dish antennas has been set-up at Cachoeira Paulista, Brazil (Longitude: 45°0′20″W, Latitude: 22°41′19″S) for observations of Sun and some of the strong sidereal sources by the Instituto Nacional de Pesquisas Espaciais (INPE), Brazil. This is Phase-1 of the proposed Brazilian Decimetre Array (BDA) and can be operated at any frequency in the range 1.2–1.7GHz. The instrument is functional since November 2004 onwards at 1.6GHz. The angular and temporal resolution at the above frequency range are ∼3′ and 100ms, respectively. We present here the initial solar observations carried out with this array.
