在艾德蒙頓(Edmonton),阿爾伯塔省,加拿大,地球上的另一個行星正躺在地平線上。這個全景合成影像的堆疊展示了一個雄心勃勃的攝影項目,按照月份的時間序列從上到下排列,追蹤從六月至十二月至下一年六月至冬至的日出點南北擺動的情況。它同時也記錄了對應的滿月升起,儘管這一點更難以追蹤。然而,這些滿月的升起在地平線上的範圍比日出來得更廣。這個周全計劃的項目(如視頻所示)覆蓋了2024年六月至2025年六月的時期,圍繞著一個重大的月球渺站(lunar standstill)。重大的月球渺站代表著月亮升起在南北範圍的極端,這是由於月球軌道的18.6年歲差週期所驅動。

dmonton, Alberta, Canada, planet Earth lies on the horizon. in this stack of panoramic composite images. In a monthly time series arranged vertically top to bottom the ambitious photographic project follows the annual north-south swing of sunrise points, from June solstice to December solstice and back again. It also follows the corresponding, but definitely harder to track, Full Moon rise. Of course, the north-south swing of moonrise runs opposite sunrise along the horizon. But these rising Full Moons also span a wider range on the horizon than the sunrises. That’s because the well-planned project (as shown in this video) covers the period June 2024 to June 2025, centered on a major lunar standstill. Major lunar standstills represent extremes in the north-south range of moonrise driven by the 18.6 year precession period of the lunar orbit.
