Major Lunar Standstill 2024-2025 Image Credit & [3]Copyright: [4]Luca Vanzella, [5]Alister Ling Explanation: [6]Edmonton, 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 [7]the ambitious photographic project follows the annual north-south swing of sunrise points, from [8]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 ([9]as shown in this video) covers the period June 2024 to [10]June 2025, centered on a major lunar standstill. [11]Major lunar standstills represent extremes in the north-south range of moonrise driven by the [12]18.6 year precession period of the lunar orbit.
