Abstract

Solar activity has a cycle of about 11 years which is related to the appearance of sunspots. Besides spots, other solar phenomena are also related to solar activity such as coronal mass ejections and solar flares. Solar flares produce radiation at various wavelengths, including radio waves of high frequency. The goal of this project is to detect as many solar flares as possible and build their radio spectrum. The importance of a good coverage of the radio spectrum, with simultaneous observations at various wavelengths, is to distinguish the different emission mechanisms present in a solar flare. To study the flares, we will use the telescopes POEMAS (POlarization of Emission of Millimeter Activity at the Sun) that monitors the Sun at 45 and 90 GHz with polarization measurements. The radio observations will be supplemented by data of the microwave network RSTN (1-15 GHz) and at high frequencies (212 and 405 GHz) when detected by the Submillimeter Solar Telescope ( SST ) .
