10 月 14 日，很難捕捉到彗星 C/ 2023 A 3 Tsuchinshan-ATLAS 的全貌。不過，在彗星最接近我們的星球之後拍攝的這幅晚間天象圖幾乎做到了這一點。從亞利桑那州圖森市的蓋茨隘口向西望去，兩幅長焦照片組合在一起，畫面從上到下橫跨天空約 26 度。當晚，彗星觀測者甚至可以辨認出球狀星團 M 5 和週期性彗星 13 P Olbers 的微弱身影，它們就在月神山-ATLAS 的白色塵埃尾跡附近，位於明亮彗星的彗尾上方。由於地球在穿越彗星軌道面時的視角原因，月琴山-ATLAS 還有一個明顯的反尾。反尾由先前釋放出來的塵埃組成，並沿著彗星軌道向遠離太陽的方向延伸，在明亮的彗尾下方可以看到針狀的延伸，朝向崎嶇的西方地平線。 成長相簿： 2024 年的月琴山-ATLAS 彗星
原文：On October 14 it was hard to capture a full view of Comet C/2023 A3 Tsuchinshan-ATLAS. Taken after the comet's closest approach to our fair planet, this evening skyview almost does though. With two telephoto frames combined, the image stretches about 26 degrees across the sky from top to bottom, looking west from Gates Pass, Tucson, Arizona. Comet watchers that night could even identify globular star cluster M5 and the faint apparition of periodic comet 13P Olbers near the long the path of Tsuchinshan-ATLAS's whitish dust tail above the bright comet's coma. Due to perspective as the Earth is crossing the comet's orbital plane, Tsuchinshan-ATLAS also has a pronounced antitail. The antitail is composed of dust previously released and fanning out away from the Sun along the comet's orbit, visible as a needle-like extension below the bright coma toward the rugged western horizon.
