Abstract

We present a preliminary analysis of a flare event that took place on 3 June 2021 at 01:36 UT. It was observed in microwaves by the Siberian Radioheliograph (SRH) within 3–6 GHz and by the Broadband Microwave Spectropolarimeter (BBMS), and in the meter-wavelength range by the e-Callisto spectrometer network. We found several type III bursts and a type-J burst in the meter-wavelength range. At the same time, only one burst was detected in the averaged time profiles of microwave emission. This one corresponds to the strongest type III radio burst. Using images from the SRH, we defined two sources and separately analysed their time profiles. This approach allowed us to find microwave bursts associated with radio bursts, which were indistinguishable in the averaged time profiles. The observed delays between the microwave and meter-wavelength emissions were compared with the results of a preliminary analysis of dynamic spectra in the meter-wavelength range.

2021年6月3日太阳耀斑微波与米波长辐射关系的研究

我们对发生在2021年6月3日01:36 UT的耀斑事件进行了初步分析。在3-6 GHz的微波波段，用西伯利亚日光照相仪(SRH)和宽带微波偏振谱仪(BBMS)和e-Callisto光谱仪网络分别对其进行了观测。我们在米波长范围内发现了几个III型爆发和一个j型爆发。同时，在微波发射的平均时间分布中只检测到一次爆发。这个对应的是最强的III型射电暴。利用SRH的图像，我们定义了两个源，并分别分析了它们的时间分布。这种方法使我们能够找到与无线电爆发相关的微波爆发，它们在平均时间分布中是无法区分的。将观测到的微波和米波长发射之间的延迟与米波长范围内动态光谱的初步分析结果进行了比较。
