How a Total Solar Eclipse Ended

Explanation: How does a total solar eclipse end? Yes, the Moon moves out from fully blocking the Sun, but in the first few seconds of transition, interesting things appear. The first is called a diamond ring. Light might stream between mountains or through relative lowlands around the Moon’s edge, as seen from your location, making this sudden first light, when combined with the corona that surrounds the Moon, look like a diamond ring. Within seconds other light streams appear that are called, collectively, Bailey’s beads. In the featured video, it may seem that the pink triangular prominence on the Sun is somehow related to where the Sun begins to reappear, but it is not. Observers from other locations saw Bailey’s beads emerge from different places around the Moon, away from the iconic triangular solar prominence visible to all. The video was captured with specialized equipment from New Boston, Texas, USA on April 8, 2024.

说明: 日全食是如何结束的？没错，月亮会从完全遮住太阳的位置移开，不过在过渡的最初几秒里，会出现一些有趣的景观。首先是会出现钻石环。阳光可能会从月缘山峰之间的低谷、或较低的凹地穿过，而从你所在的位置看出去，这种突然出现的首道光和环拱月亮的日冕合起来，组合成一枚钻石戒指。紧接着在数秒里，其他束状的阳光也会出现，形成倍里珠的景观。在这幅主题影片里，粉红的三角日冕看似也和太阳复圆的过程有关，但实情并非如此。而位于其他地点的观察者，在月缘看到的倍里珠，其位置相对于众所共见的三角日冕也有不同。这部使用特殊设备拍摄的影片，是在2024年4月8日摄于美国德州的新波士顿镇。
