Description
Summary:Solar radio burst at low-frequency lies in the fact that they originate in the same layers of the solar atmosphere in which geo-effective disturbance probably originate Type III bursts have consistently the fastest drift rates of bursts at metric wavelengths and was created by an electron beam through plasma emission. Meanwhile, type IV burst is broadband quasi-continuum features associated with the decay phase of solar flares. A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth. The aim of this study is to find out whether type III bursts preserved energy to solar bursts type IV thus led to the formation of geomagnetic storm. The solar radio burst type III and IV were observed by CALLISTO Spectrometer. CALLISTO is an acronym from Compound Astronomical Low cost Low frequency Instrument for Spectroscopy and Transportable Observatory. The Sunpy by Python was used to analyze the spectrogram image by eliminate the unwanted signal or noise in the image which is in the presence of noise, the spectrum gives inaccurate reading of frequency and time. Although the study did not show much correlation between bursts type IV and type III in producing these storms, there are several possible explanations from this result. It may be the case that solar events such as solar flare, CMEs and active region ejected from the solar disc is not heading towards Earth and the energy has eventually disperses into the interplanetary medium.
