Explanation: Will the sky be clear enough to see the eclipse? This question is already on the minds of many North Americans hoping to see tomorrow’s solar eclipse. This question was also on the mind of many people attempting to see the total solar eclipse that crossed North America in August 2017. Then, the path of total darkness shot across the mainland of the USA from coast to coast, from Oregon to South Carolina — but, like tomorrow’s event, a partial eclipse occurred above most of North America. Unfortunately, in 2017, many locations saw predominantly clouds. One location that did not was a bank of the Green River Lakes, Wyoming. Intermittent clouds were far enough away to allow the center image of the featured composite sequence to be taken, an image that shows the corona of the Sun extending out past the central dark Moon that blocks our familiar Sun. The surrounding images show the partial phases of the solar eclipse both before and after totality.

说明: 天空是否清朗到可以观赏日食呢？想观赏明天的日全食的北美洲住民之心中，这将是一个挥之不去的疑问。而于2017年8月，同样的问题也浮现在北美洲各地想看日食人们的脑海里。在当年，全食带从美国本土西岸的奥勒冈州绵延西东两岸至南卡罗莱纳州，而且与明天类似，大部分的北美洲至少能见到日偏食。不过很遗憾的，许多人在2017年基本上只见到乌云。能看到日食的地点之一，是上面影像所呈现的怀俄明州的绿河湖岸边。在该地，乌云断断续续的遮住太阳，直到全食阶段的前1分钟，乌云才退开到得以拍下上面这幅组合主题影像序列。影像中，当月盘完全遮住太阳时，明亮的日冕从中央黝黑月盘的边缘伸出。而摄于日全食前及后的影像，则呈现了食甚阶段前后的日偏食。
