CALLISTO Facilities in Peru: Spectrometers Commissioning and Observations of Type III Solar Radio Bursts

Abstract

The Astrophysics Directorate of CONIDA has installed two radio spectrometer stations belonging to the e-CALLISTO network in Lima, Peru. Given their strategic location near the Equator, it is possible to observe the Sun evenly throughout the whole year. To calibrated the antennas we analyzed the radio ambient background and measured their radiation pattern and beam-width. The stations took data from 2014 until 2016 in the metric and decimetric bands looking for radio burst. To understand the solar dynamics in these radio frequencies we have selected and analyzed type III Solar Radio Bursts candidates. The study of these bursts helps to understand the electron beams traversing the solar corona and the solar atmospheric density. We have obtained standard mean values for the associated plasma parameters with a starting negative frequency drift rate JARengifo
