这次日全食不仅具有诗意的美丽，而且在科学上也很有趣。通常情况下，日冕是白色的，对于一些观测者来说，上周日全食的日冕确实呈现出这种珍珠色。但这一次，西班牙的日全食观测者看到了一个异常金色的日冕。原因之一是，在西班牙，日全食发生在日落接近地平线的时候。那么低，阳光穿过大量的空气，散射出蓝光。附近森林大火产生的异乎寻常的烟雾充当了第二个过滤器，进一步散射了剩余的蓝色调，加深了本已以金色为主的光线。这张经过hdr处理、多次曝光的特色图片是上周在西班牙贝纳文特拍摄的。有一样东西没有呈现出金色，那就是盘旋在太阳左边缘的一个氢发光的日珥——它原来的亮粉色保留了下来。图集：2026年8月12日的日食

This total solar eclipse appeared not only poetically beautiful but scientifically interesting. Usually the solar corona appears white, and to some observers the corona of last week's total solar eclipse did appear this pearly color. But this time, totality observers in Spain saw a corona that appeared unusually golden. For one reason, from Spain, the totality occurred when the setting Sun was near the horizon. That low, sunlight travels through a large amount of air which scatters out blue light. An unusual amount of smoke in the air from nearby forest fires acted as a second filter, further scattering the remaining blue tones and deepening the already gold-dominated light. The HDR-processed, multiple-exposure featured image was captured from Benavente, Spain last week. One thing that did not appear golden was a hydrogen-glowing prominence that hovered over the Sun's left edge -- its original bright pink color survived. Gallery: Solar Eclipse of 2026 August 12
