SOLARIS: a network of telescopes for solar imaging at high radio frequency and space weather applications

Solaris is a scientific and technological project aimed at the development of a smart Solar monitoring system at high radio frequencies based on innovative single-dish imaging techniques, recently approved as a permanent observatory in Antarctica. It combines the implementation of dedicated and interchangeable high-frequency receivers on existing small single-dish radio telescope systems (1.5/2.6m class) available in our laboratories, in the Alps and in Antarctica, to be adapted for Solar observations. Operations in Antarctica will offer unique observing conditions (very low sky opacity and long Solar exposures) and unprecedented Solar monitoring in radio W-band (70-120 GHz). This will be achieved through state-of- the-art single-dish imaging techniques at radio frequencies, that allows us to map the entire Solar disk in less than 30 min with spatial resolution of a few arcminutes. This opens for the identification and spectral analysis of Active Regions before, after and during the occurrence of Solar flares.
