Striated twilight glows have been observed since 26 November 1974 in New England, indicating the spread of stratospheric dust earlier observed over Arizona. Similar photometric results were obtained from New Mexico and Florida, and twilights in Puerto Rico showed features not hitherto measured. Letters and verbal reports indicate the source to be eruptions of Fuego Volcano in Guatemala between 13 and 23 October 1974.
自 1974 年 11 月 26 日以来，新英格兰地区一直观察到条纹暮光辉光，表明平流层尘埃的扩散早于亚利桑那州观察到的尘埃。新墨西哥州和佛罗里达州也获得了类似的光度结果，而波多黎各的暮光辉光则显示出迄今未测量到的特征。信件和口头报告表明，这一现象的来源是 1974 年 10 月 13 日至 23 日危地马拉富埃戈火山的喷发。
