Annular Solar Eclipse over Utah

Explanation: Part of the Sun disappeared earlier this month, but few people were worried. The missing part, which included the center from some locations, just went behind the Moon in what is known as an annular solar eclipse. Featured here is an eclipse sequence taken as the Moon was overtaking the rising Sun in the sky. The foreground hill is Factory Butte in Utah, USA. The rays flaring out from the Sun are not real — they result from camera aperture diffraction and are known as sunstar. The Moon is real, but it is artificially brightened to enhance its outline — which helps the viewer better visualize the Moon’s changing position during this ring-of-fire eclipse. As stunning as this eclipse sequence is, it was considered just practice by the astrophotographer. The reason? She hopes to use this experience to better photograph the total solar eclipse that will occur over North America on April 8, 2024.

说明: 在这个月初，部分的太阳消失，不过却鲜少有人担心。日盘之所以会发生缺角，甚至从某些地方看出去，整个太阳中心都不见了，其实是太阳藏在月亮的后头所产生的日环食景观。在这幅摄于月亮追过东升旭日期间的主题日食影像序列里，前景的山丘是美国犹他州的工厂丘。此外，从太阳伸出的辐射光束并不是真的，它们是因相机光圈所产生的、名为太阳星的衍射景象。其中的月亮倒是真的，只不过也经为人为增亮以强化其轮廓，让读者更容易辨识此次火之环食期间月亮位置的变化。不管这个日食影像序列如何引人赞叹，然而对这位天文摄影者而言，这仅是练习作而已。原因何在？她希望借着此次经验，为2024年4月8日拍下北美洲日全食精采影像的工作预做热身。 （Factory Butte 工厂丘）
