9月的月全食在地球南北半球的夜空中被记录下来，这是两个戏剧性的延时系列。在北半球序列（上图）中，月球的轨迹从左上到右下呈弧形。它经过明亮的土星下方，在北纬30度左右的中国浙江大学国际校区，在晴朗的天空下可以看到它。相比之下，在南纬35度的澳大利亚堪培拉格里芬湖拍摄的南半球照片，从右上到左下记录了月球的轨迹。地平线附近的雷暴产生的多道闪电出现在湖面上。这两组照片都是用16毫米广角镜头拍摄的，都覆盖了整个日食，暗红色的月亮完全沉浸在地球的本影中，接近中心。但是，月球在天空中路径的不同方向揭示了南北纬度视角的变化。

September's total lunar eclipse is tracked across night skies from both the northern and southern hemispheres of planet Earth in these two dramatic timelapse series. In the northern hemisphere sequence (top panel) the Moon’s trail arcs from the upper left to the lower right. It passes below bright planet Saturn, seen under mostly clear skies from the international campus of Zhejiang University in China at about 30 degrees north latitude. In contrast, the southern hemisphere view from Lake Griffin, Canberra, Australia at 35 degrees south latitude, records the Moon’s trail from the upper right to the lower left. Multiple lightning flashes from thunderstorms near the horizon appear reflected in the lake. Both sequences were photographed with 16mm wide-angle lenses and both cover the entire eclipse, with the darkened red Moon totally immersed in Earth's umbral shadow near center. But the different orientations of the Moon’s path across the sky reveal the perspective shifts caused by the views from northern vs. southern latitudes.
