论文摘要
Conida的天体物理局已经安装了秘鲁利马E-Callisto网络的两个无线电光谱仪站。鉴于他们在赤道附近的战略位置，可以在全年中均匀地观察太阳。位于首都利马附近的普卢卡纳的接收器从2014年10月到2016年8月在公制和十二式乐队中获取数据。在此期间，该电子 - 加利斯托探测器的时区覆盖范围是独一无二的。为了评估位点的适用性和天线的性能，我们分析了无线电环境背景，并测量了它们的辐射模式和梁宽。为了显示设施在这些无线电频率中研究太阳动力学的功能，我们选择并分析了III型太阳能无线电爆发。对这种爆发的研究有助于理解横穿太阳电晕和太阳大气密度的电子束。我们已经表征了最常见的无线电爆发，其平均值为-25.8 $ \ pm $ 3.7 MHz/s，持续时间为2.6 $ \ pm $ 0.3 s和35 MHz带宽，在114至174 MHz的频率范围内。此外，对于某些事件，可以计算出平均为0.4 $ \ pm $ 0.1 MHz/s的全局频率漂移。
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. The receiver located at Pucusana, nearby the capital city of Lima, took data from October 2014 until August 2016 in the metric and decimetric bands looking for radio bursts. During this period, this e-CALLISTO detector was unique in its time-zone coverage. To assess the suitability of the sites and the performance of the antennas we analyzed the radio ambient background and measured their radiation pattern and beam-width. To show the capabilities of the facilities to study solar dynamics in these radio frequencies we have selected and analyzed type III Solar Radio Bursts. The study of this kind of bursts helps to understand the electron beams traversing the solar corona and the solar atmospheric density. We have characterized the most common radio bursts with the following mean values: a negative drift rate of -25.8 $\pm$ 3.7 MHz/s, a duration of 2.6 $\pm$ 0.3 s and 35 MHz bandwidth in the frequency range of 114 to 174 MHz. In addition, for some events, it was possible to calculate a global frequency drift which on average was 0.4 $\pm$ 0.1 MHz/s.
