Abstract. This article summarizes the results of an analysis of solar radio bursts detected by the e-Compound Astronomical Low cost Low-frequency Instrument for spectroscopy and Transportable Observatory (e-CALLISTO) spectrometer hosted by the University of Rwanda, College of Education. The data analysed were detected during the first year (2014–2015) of the instrument operation. The Atmospheric Imaging Assembly (AIA) images on board the Solar Dynamics Observatory (SDO) were used to check the location of propagating waves associated with type III radio bursts detected without solar flares. Using quick plots provided by the e-CALLISTO website, we found a total of 202 solar radio bursts detected by the CALLISTO station located in Rwanda. Among them, 5 are type IIs, 175 are type IIIs, and 22 type IVs radio bursts. It is found that all analysed type IIs and ∼37 % of type III bursts are associated with impulsive solar flares while Type IV radio bursts are poorly associated with flares. Furthermore, all of the analysed type II bursts are associated with CMEs which is consistent with the previous studies, and ∼44 % of type IIIs show association with CMEs. On the other hand it is observed that the majority of type IV radio bursts are believed to be originated from CME-driven shocks. Findings from this study confirms that solar radio bursts (SRBs) from ground observation and analysis constitute a clue to diagnose the space weather phenomena such as solar flare and CMEs and to some extent, they may serve as the advance warning of the related severe space weather hazards.

通过单站CALLSTO光谱仪检测到的太阳射电爆发分析进行空间天气研究

摘要。本文总结了由卢旺达大学教育学院主办的电子复合天文低成本光谱仪和可移动天文台（e-CALLISTO）光谱仪检测到的太阳无线电脉冲的分析结果。在仪器运行的第一年（2014-2015年）检测到分析的数据。太阳动力学天文台（SDO）上的大气成像组件（AIA）图像用于检查与没有太阳耀斑的III型无线电脉冲有关的传播波的位置。使用e-CALLISTO网站提供的快速绘图，我们发现位于卢旺达的CALLISTO站检测到总共202个太阳无线电脉冲。其中，II型5个，III型175个，IV型22个无线电脉冲串。发现所有分析过的II型爆发和〜37％的III型爆发与脉冲太阳耀斑有关，而IV型无线电爆发与耀斑无关。此外，所有已分析的II型爆发与CME有关，这与先前的研究一致，并且约44％的III型爆发与CME有关。另一方面，可以观察到，大多数IV型无线电脉冲被认为源自CME驱动的电击。这项研究的结果证实，从地面观察和分析得出的太阳无线电爆发（SRB）构成了诊断诸如太阳耀斑和CME之类的空间天气现象的线索，并且在某种程度上，它们可以作为有关严重的空间天气的预警。危害。
