Observations of Low Frequency Solar Radio Bursts from the Rosse Solar-Terrestrial Observatory

The Rosse Solar-Terrestrial Observatory (RSTO) was established at Birr Castle, Co. Offaly, Ireland in 2010 to study solar radio bursts and the response of the Earth's ionosphere and geomagnetic field. To date, three Compound Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory (CALLISTO) spectrometers have been installed, with the capability of observing in the frequency range 10-870 MHz. The receivers are fed simultaneously by biconical and log-periodic antennas. RSTO is optimized to record dynamic spectra of Type II, III and IV radio bursts. In particular, fine-scale structure such as herringbones and Type II band splitting can be detected by RSTO. Here we describe RSTO instrumentation and present some example-spectra.
