论文摘要
2020年6月21日，在香港的小型望远镜21厘米的小型射电望远镜以0.89的幅度进行研究。射程望远镜蜘蛛300A由意大利的Radio2Space Company设计和建造。本文介绍了无线电密度的时间曲线（光曲线）和日食的二维映射。标准无线电数据还原方法用于获得强度时间曲线。我们还采用了半高管方法来减少数据，以获得与射电望远镜蜘蛛300A的内置软件相同的结果。 Eclipse的总太阳能无线电通量最大减少了55 +/- 5％，而同一日食的最大蚀面积为86.08％。本文还讨论了香港太阳日食的其他无线电观察结果，包括2019年12月26日对部分日食的蜘蛛300A观察（附录A）；以及由美国麻省理工学院的Haystack天文台开发的小型射电望远镜（SRT），观察到2020 Eclipse（附录B）。
Small radio telescope in 21cm was used for studying the partial solar eclipse, with magnitude 0.89, in Hong Kong on 21st June, 2020. The radio telescope SPIDER 300A was designed and constructed by the Radio2Space Company, Italy. Radio flux density time curves (light curve) and a two-dimension mapping of the eclipse is presented in this paper. Standard radio data reduction methods were used to obtain the intensity time curve. We also adopted the semi-pipeline method for the reduction of data to obtain the same results as with the built-in software of the radio telescope SPIDER 300A. The total solar radio flux of the eclipse was found to reduce by maximum 55 +/- 5 percent, while the maximum eclipsed area of the same eclipse is 86.08%. Other radio observations of solar eclipses in Hong Kong are also discussed in this paper, including SPIDER 300A observation of partial solar eclipse on 26th December 2019 (APPENDIX A); and small radio telescope (SRT), developed by the Haystack Observatory, MIT, USA, observation of 2020 eclipse (APPENDIX B).
