Application of Solar Radio Bursts Observation in Detecting Magnetic Reconnection Phenomenon

Abstract

Abstract This study highlights the importance of solar activity observation in radio region which covers 45-870 MHz, which also provides clues on the appearance of magnetic reconnection. It was carried out by utilizing e-CALLISTO data from Glasgow station. On 9th March 2019, intense solar radio bursts type III sparked off and were detected by Glasgow station in the UK at 12.29 UT, that lasted for 15 minutes. There were two bursts that were observed to appear separately by 1-minute interval. Accompanying the bursts formation was a B6.5 flare, the highest flare throughout the day and it was recorded by NOAA at 12.26 UT which was in the time frame of the bursts event. It is believed that the type III bursts were associated to the flare formation as radio emissions were emitted at the beginning of the flare during reconnection. From the analysis, results have shown that multiple magnetic reconnection process took place during the solar activity as indicated by a large group of bursts. However, no extended bursts formed for the rest of the day as well as lack of activity produced by the same region for the following days and that could be a hint of the decay phase of AR 2734. Detailed discussions on the bursts corresponding to the flare activity are discussed in this paper.
