持续8分30秒的日全食

2019 July 6 持续8分30秒的日全食 影像提供与版权: Bob Minor 说明: 在7月2日的日食期间,全食阶段最长约可持续4分30秒。能见到这个最长全食的地点,在地球表面·复活岛北方大约1,100公里的南太平洋面上。不过,如果位在和月食交错,离地表11,277公尺的包机上,月亮完全遮住太阳的期间可拉长到8分30秒。当时位在食甚拦截点的这部飞机,在顺风相助之下,大约以900公里的时速沿着全食带追月。摄影者从云层上方的飞机向阳靠窗坐位,拍下这幅的壮观大视野影像,并记录了悬在机翼上方的全食日和荧荧日冕。 8 Minute and 30 Second Eclipse Image Cred

拉西亚天文台的日食系列影像

2019 July 5 拉西亚天文台的日食系列影像 影像提供与版权: Petr Horálek 说明: 前往峰顶拉西亚天文台的引道,恰好也在7月2日全食的全食带上,所以看似指向全食日。这个寻常的日食序列,中心点在月球的暗影,恰好盖住数部地球数部最大型望远镜之瞬间。事实上,拉西亚天文台在全食带中心线偏北一点的位置。因此,这片异常澄澈的天空,右侧(北方)的区域较为明亮。这个梦境般的景观,西眺落日与全食带月影飞掠而来的方向。 La Silla Eclipse Sequence Image Credit & Copyright: Petr Horálek Explanation: The ro

站在月球的影子里

2019 July 4 站在月球的影子里 影像提供与版权: Yuri Beletsky (Carnegie Las Campanas Observatory, TWAN) 说明: 在2019年7月2日的南美洲日全食期间,地球的住民可伫足在月球黝黑的本影里。月球本影和地面的初始接触点,在纽西兰东方的太平洋面,然后沿狭窄的路径向东飞掠,当太阳低垂在西方地平线上空时,本影恰好切过智利的太平洋岸。在上面这幅影像里,在食甚之前的瞬间,最后一丝漏过的阳光,曳出了前景的长长影子。而转瞬将进入全食阶段的太阳,在幽暗明澈的天空中,形似美丽的钻石环。太阳边缘的绕射芒,则是由相机镜头的光圈所造成的。 In the
