Abstract:
Colombia is located in the northern tip of South America close to the amazon rain forest. This makes astronomical observations in the visible range very challenging, as cloud coverage is relatively high. Hence, radio astronomy becomes a natural and good choice. We present the design, characterization and first results of the Observatorio Astronomico Nacional solar radio spectrograph. This instrument is a Log-Periodic Dipole Array Antenna (LPDA) working between 100 MHz and 1 GHz optimized for solar observations. The radio spectrograph is a working prototype for a more ambitious solar radio interferometer, that will be the first instrument of this kind in Colombia.
