A Ring of Fire Sunrise Solar Eclipse

Explanation: What’s rising above the horizon behind those clouds? It’s the Sun. Most sunrises don’t look like this, though, because most sunrises don’t include the Moon. In the early morning of 2013 May 10, however, from Western Australia, the Moon was between the Earth and the rising Sun. At times, it would be hard for the uninformed to understand what was happening. In an annular eclipse, the Moon is too far from the Earth to block the entire Sun, and at most leaves a ring of fire where sunlight pours out around every edge of the Moon. The featured time-lapse video also recorded the eclipse through the high refraction of the Earth’s atmosphere just above the horizon, making the unusual rising Sun and Moon appear also flattened. As the video continues on, the Sun continues to rise, and the Sun and Moon begin to separate. This weekend, a new annular solar eclipse will occur, visible from central Africa, the Arabian Peninsula, and a narrow band across Asia, with much of Earth’s Eastern hemisphere being able to see a partial solar eclipse.

日出带环食

说明:在地平线缓缓升起的是什么?太阳!不过,大部分的日出并非如此,因为日常东升的太阳不会有月亮为伴。在2013年5月10日的清晨,从西澳大利亚看出去,月亮位在地球和东升的太阳之间。当时东升的旭日不但受到月亮的掩食,也时时受到地球浮的遮掩,因此不知情者难以辨其本尊。日环食之所以会发生,是因为月亮离地球太远而无法遮住整个日盘,在食甚时,阳光从月盘所有的边缘漏出来,形成了火之环的景观。这部主题缩时影片,穿过地平面上空高折射、让东升的太阳和月亮都变扁的地球大气,记录了此次日食的历程。随着影片不停播放,太阳也不停的攀高,最后太阳和月亮开始分离。这个周末将再次出现日环食,可见的区域包括中非洲、阿拉伯半岛、以及一道穿过亚洲的狭窄食带,而其他东半球的大部分区域将可观赏日偏食。
