While observing the 21 August 2017 total solar eclipse from Shoshoni, Wyoming, the author briefly witnessed an annulus of red light 2° to 3° from the center of the totally eclipsed sun. The author had no prior knowledge of this phenomenon, thus reducing the chances of observational bias. A simple experiment suggests that the phenomenon may not be the result of an afterimage illusion produced by observing the eclipse through binoculars. The results of these observations appear to support the CCD color measurements of the sky during the same eclipse observed from Esterbrook, Wyoming, by Bruns and Bruns [Appl. Opt.57, 4590 (2018)APOPAI0003-693510.1364/AO.57.004590].
2017年8月21日，作者在怀俄明州肖肖尼观测日全食时，短暂目睹了一个位于日全食太阳中心2°至3°处的红光环。作者此前并不了解这一现象，从而降低了观测偏差的可能性。一项简单实验表明，该现象可能并非通过双筒望远镜观测日食产生的余像错觉所致。这些观测结果似乎支持了布伦斯和布伦斯在怀俄明州埃斯特布鲁克观测同一日食期间对天空进行的电荷耦合器件（CCD）颜色测量结果[《应用光学》57, 4590 (2018)APOPAI0003 - 693510.1364/AO.57.004590]。
