太阳能同时升起两次吗？这就是几天前在加拿大魁北克省的Les Escoumins发生的情况，当时我们太阳系明亮的中央球体正在被月球部分遮蔽时上升。这段特色视频实时展示了这种不寻常的双重日出，并被圣劳伦斯河反射出来。在最初的两个光点出现在遥远的云层上后不久，看起来是明亮的角状物就变得可见了——这实际上只是太阳没有被遮挡的部分。很快，整个日食的太阳就可以在地平线上看到了。总的来说，在日偏食持续的时间比日偏食长很多倍的情况下，这个破碎的日出只用了不到两分钟。虽然月球每月绕地球一周，但它并不总是日食太阳，因为它倾斜的轨道通常是在上面或下面。画廊：2025年3月的日偏食

Can the Sun appear to rise twice at the same time? This was just the case a few days ago from Les Escoumins, Quebec, Canada as our Solar System's bright central orb rose just as it was being partially eclipsed by the Moon. The featured video shows this unusual double-sunrise in real time and being reflected by the St. Lawrence River. Soon after the initial two spots of light appear over distant clouds, what appears to be bright horns become visible -- which are really just parts of the Sun not being eclipsed. Soon, the entire eclipsed Sun is visible above the horizon. In all, this broken sunrise took less than two minutes during a partial eclipse that lasted many times longer. Although the Moon circles the Earth once a month (moon-th), it does not always eclipse the Sun because its tilted orbit usually takes it above or below. Gallery: Partial Solar Eclipse of 2025 March
