在這組全景合成影像中,地球位於加拿大阿爾伯塔省 dmonton 的地平線上。在從上到下垂直排列的每月時間序列中,這個雄心勃勃的攝影專案追隨著每年日出點的南北擺動,從 6 月至日到 12 月至日,再從 12 月至日回到 6 月至日。同時,它還跟蹤了相應的、但絕對更難跟蹤的滿月日出。當然,月亮升起的南北擺動與地平線上的日出相反。不過,與日出相比,這些升起的滿月在地平線上的範圍也更廣。這是因為這個精心策劃的專案(如本影片所示)覆蓋了 2024 年 6 月到 2025 年 6 月這段時間,其中心是月球大停滯。月大停滯代表著月球軌道 18 . 6 年的偏前週期所導致的月出南北範圍的極端。
原文: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.
