2026年8月20日，西班牙经历的日全食中出现了不寻常的金色日冕现象1。这次天文奇观发生在日落时分，当太阳光线需要穿过更厚的大气层时，大气对光线的散射改变了日冕的外观1。
金色日冕的形成受到多重因素影响1。除了日落时分大气层增厚导致的光学效应外，附近野火烟雾进一步散射移除了蓝光成分，使原本呈银白色的日冕转变为金色1。同时，观测者还能看到粉红色的太阳物质凸起结构，这些凸起由氢元素的光线发射而成1。
A total solar eclipse that occurred over Spain on August 20, 2026, produced an unusually golden corona instead of the typical silvery-white appearance normally observed during such events 1. The eclipse reached totality during sunset, causing sunlight to pass through a thicker layer of Earth's atmosphere, which altered the appearance of the sun's outer corona 1. Additional filtering from smoke generated by nearby wildfires further scattered blue light wavelengths, intensifying the golden hue of the corona 1.
Observers in Benavente, Spain captured the phenomenon, which also revealed pink-colored solar prominences—ejections of solar material composed of hydrogen—visible against the darkened sky 1. The combination of atmospheric thickness at sunset and smoke particles from regional fires created conditions that selectively removed shorter blue wavelengths from the light reaching the corona, leaving behind the warmer golden tones that made this eclipse visually distinctive 1.
