是的，但是你见过这样的日出吗？在这里，在最初的云层之后，太阳似乎分两部分升起，在2019年的日偏食期间，摄影师将其描述为他一生中最令人惊叹的日出。在大气中变红的太阳顶部附近的黑色圆圈是月球，但它下面的黑色峰值也是如此。这是因为在此过程中，地球大气层中有一层异常温暖的空气覆盖在海面上，就像一个巨大的透镜，产生了第二幅图像。对于正常的日出或日落，这种罕见的大气光学现象被称为伊特鲁里亚花瓶效应。这张照片是2019年12月在卡塔尔Al Wakrah拍摄的。一些观测者在地球东部的狭窄地带能够看到一个完整的日环食——月球看起来完全被背景太阳包围在一个火环中。下一个日食，对于位置好的观测者来说也是一次日环食，将在本周六发生。APOD编辑发言：10月12日星期四下午6点在密歇根州霍顿

Yes, but have you ever seen a sunrise like this? Here, after initial cloudiness, the Sun appeared to rise in two pieces and during a partial eclipse in 2019, causing the photographer to describe it as the most stunning sunrise of his life. The dark circle near the top of the atmospherically-reddened Sun is the Moon -- but so is the dark peak just below it. This is because along the way, the Earth's atmosphere had a layer of unusually warm air over the sea which acted like a gigantic lens and created a second image. For a normal sunrise or sunset, this rare phenomenon of atmospheric optics is known as the Etruscan vase effect. The featured picture was captured in December 2019 from Al Wakrah, Qatar. Some observers in a narrow band of Earth to the east were able to see a full annular solar eclipse -- where the Moon appears completely surrounded by the background Sun in a ring of fire. The next solar eclipse, also an annular eclipse for well-placed observers, will occur this coming Saturday. APOD editor to speak: in Houghton, Michigan on Thursday, October 12 at 6 pm
