今晚日落的时候出去看看彗星吧！C/2023 A3 （Tsuchinshan-ATLAS）已经在北部地区的傍晚天空中肉眼可见。要看到这颗彗星，要穿过低地平线的天空向西看。如果天空足够晴朗和黑暗，你甚至不需要双筒望远镜——彗星微弱的尾巴应该可以在地平线上看到大约一个小时。图中是两晚前在美国华盛顿特区林肯纪念堂上空拍摄到的彗星Tsuchinshan-ATLAS。随着每一天的日落，这颗彗星和它不断变化的尾巴应该在天空中越来越高，尽管它的尾巴究竟有多亮、有多长只能猜测。正在成长的画廊：2024年的土钦山彗星- atlas

Go outside at sunset tonight and see a comet! C/2023 A3 (Tsuchinshan–ATLAS) has become visible in the early evening sky in northern locations to the unaided eye. To see the comet, look west through a sky with a low horizon. If the sky is clear and dark enough, you will not even need binoculars -- the faint tail of the comet should be visible just above the horizon for about an hour. Pictured, Comet Tsuchinshan-ATLAS was captured two nights ago over the Lincoln Memorial monument in Washington, DC, USA. With each passing day at sunset, the comet and its changing tail should be higher and higher in the sky, although exactly how bright and how long its tails will be can only be guessed.
