這組跨越一年的影像記錄於 2024 年,揭示了太陽每天在地球天空中運動的季節性漂移模式。這條八字形曲線被一些人稱為 "日珥"(analemma),僅在晴天當地時間下午 1 點從土耳其開塞利拍攝的曝光中捕捉到。當然,太陽在 2024 年至日的位置位於曲線的頂部和底部。它們分別對應著天文學上北方夏季和冬季的開始。沿曲線在至日之間的中點,但不是八字形曲線的交叉點,標誌著 2024 年春分和秋分的開始。在 2024 年延時拍攝的天景中,地區性山峰和休眠火山 Erciyes 山位於南部地平線上。
原文:Recorded during 2024, this year-spanning series of images reveals a pattern in the seasonal drift of the Sun's daily motion through planet Earth's sky. Known to some as an analemma, the figure-eight curve was captured in exposures taken only at 1pm local time on clear days from Kayseri, Turkiye. Of course the Sun's position on the 2024 solstice dates was at the top and bottom of the curve. They correspond to the astronomical beginning of summer and winter in the north. The points along the curve half-way between the solstices, but not the figure-eight curve crossing point, mark the 2024 equinoxes and the start of spring and fall. Regional peaks and dormant volcano Mount Erciyes lie along the southern horizon in the 2024 timelapse skyscape.
