紫金山天文台發現新彗星　明年或肉眼可見

國際小行星中心發布一顆新彗星C/2023 A3（Tsuchinshan-ATLAS）的確認公告。該目標由中國科學院紫金山天文台近地天體望遠鏡於1月9日首次發現，
後由南非ATLAS計劃在2月22日報告存在彗星特徵，進一步通過美國帕洛瑪ZTF望遠鏡觀測資料的回溯檢測，確認為一顆已經開始活動的彗星。

國際小行星中心將這顆彗星命名為Tsuchinshan-ATLAS/紫金山-阿特拉斯

該彗星軌道傾角約139度，是一顆逆形軌道彗星；偏心率超過0.999，在一個近拋物線的橢圓軌道上運動，軌道周期為61751年。根據目前的軌道信息，該彗星目前還處在木星軌道以外，後續將朝着它的近日點方向運動，在2024年8月穿過地球的軌道，至2024年9月28日可到水星軌道附近。隨着距離太陽越來越近，該彗星的亮度將快速增加，有望在2024年9月成為肉眼可見的大彗星。

2/25

还未编号命名的新彗星初步推算
目前绝对星等9.2，近日点时间2024年9月29日，近地点距0.389AU，最大亮度相位角146度，最大亮度4.5，因为彗星发现还处于早期活动非常微弱的阶段，根据经验最后会比这个数值亮2-4等，如果尘埃尾发达，相位角散射可增光2等左右

观测显示这颗彗星正在向内太阳系坠落，预计会在 2024 年 9 月进入距离太阳 5900 万公里的轨道，预计到 2025 年年底将抵达近日点，到时候观测起来相对来说就会容易很多。

由水冰和尘埃构成的彗星 (并非所有彗星都是如此) 在逐渐接近太阳时，水冰等物质会升华并形成长长的彗尾，到时候或许在地球上的人们也可以轻易看到这颗彗星，这类长周期彗星下次什么时候出现说不好就是几百年之后了，所以错过就只能再等待其他长周期彗星进入内太阳系。

不过在靠近太阳过程中水冰的挥发速度是无法预料的，也就是当前看起来彗星 C/2023 A3 非常明亮，但真正到了近日点可能很多水冰已经升华弥散在太空中，到时候还有没有超高的亮度就难说了。

星天日和

9/24起，阿紫將會在清晨五點左右，出現在正東方的低空（真的很低，請盡可能往高海拔、地平線附近視野佳處）；
亮度預測在4等上下，有機會能以裸眼觀測，但有雙筒望遠鏡仍佳。

9/29阿紫來到最高位置（約7°），之後開始降低，


直到10/2後再次因接近太陽而不得見。
10/13起，阿紫將在傍晚六點半左右，出現在正西方低空；
亮度可能已降至裸眼看不到的程度、需要望遠鏡輔助（結果活動都只能辦在這段時間）。
之後，仰角迅速升高（代表彗星快速遠離）、亮度也跟著降低

10/15 雙彗星 + M5

彗星C/2023 A3即將抵達近日點    _將於台灣時間9月28日1:31抵達近日點 _9月11日起，澳洲業餘天文觀測者泰瑞·洛弗喬伊(Terry Lovejoy)在澳洲昆士蘭再次拍攝到該彗星，這是地面望遠鏡再次拍到它的第一個紀錄，亮度約為5.5等，9月14日他再次拍攝到該彗星已提升至4.8等，似乎亮度仍在穩定提升，如無意外會在10月12日達到最亮，現在就看它能不能撐到越過近日點了  _ 等到9月16日以後才能逐漸在拂曉5時靠近地平線的東方看見它，隨著日期的推進，9月28日時的仰角會相對最高，但也都低於10°，接著在1週後再次降低至與太陽同升同降，現已更新9月的路徑預測圖。

違停害武嶺狂塞車！律師喊「流量密碼7080」 駕駛身分曝光

合歡山武嶺今（20）日清晨起就湧入大批遊客追彗星、等日出，造成交通壅塞，甚至有1輛黑色租賃汽車違規停車占據車道，使得車流大打結

最扯的是，現場有1輛黑色租賃汽車路邊違規停車，造成交通大打結。這台違停的汽車引發熱議，有今天上武嶺的民眾直呼，把車停在武嶺亭前面路中間，然後人就不見

現場民眾則說，卡了幾個小時最後才看到一個老外來移車！而據《中央社》報導，警方表示，黑色出租車使用人為1男、1女外籍人士，疑到附近爬山而違規停車。
