Was the face that launched a thousand ships And burnt Illium? Sweet Helen, make me immortal with a kiss! Her lips suck forth my soul, see where it flies! Come, Helen, come, give me my soul again! Here will I dwell, for heavan be in these lips, And everything is dross that is not Helena!

引用自臺北天文館網路天文館網站 http://tamweb.tam.gov.tw/news/2010/201005/news2010052204.htm搶先目睹深擊延伸任務目標─哈德利2號彗星 右圖是目前正在西班牙安達魯西亞太空物理研究所(Instituto de Astrofisica de Andalucia-CSIC) 擔任博士後研究員的彗星專家林忠義博士提供之第103號周期彗星哈德利2號(103P/Hartley 2) 與IC 1373星系接近的影像,是在2010年5月21日凌晨,以中央大學鹿天文台(Lulin Observatory) 1米望遠鏡(LOT) 加PI1300 CCD,以紅光濾鏡(R filter) 拍攝300秒的成果。 哈德利2號彗星如此受矚目原因,是因為2005年7月發射撞擊器撞擊譚普1號彗星(9P/Temple 1) 的「深擊任務太空船(Deep Impact)」,將於2010年11月4日前後近距飛掠此彗星以進行探測,屆時太空船和彗星相距僅約700公里左右,相當於2倍臺灣南北長度的距離。這是深擊計畫的延伸任務EPOXI (Extrasolar Planet Observation and Deep Impact Extended Investigation) 的其中一個子計畫,稱為DIXI (Deep Impact eXtended Investigation)。 哈德利2號彗星是在1986年3月15日,由澳洲天文學家Malcolm Hartley於塞丁泉天文台(Siding Spring)以口徑36公分的史密特-蓋塞格林式望遠鏡(Schmidt-Cassegrain telescope)發現,直徑約1.2~1.6公里,繞日公轉週期6.46年,為短週期彗星,目前只有19等左右,非常昏暗。但是,這顆彗星預計今年10月20日與地球相距僅約0.12AU,之後在10月28日以1.05AU的距離通過其軌道近日點,彗星專家預估在此期間,哈德利2號彗星亮度將可達4.5等左右,位在天鵝座中,或許以雙筒望遠鏡就可觀測,這是哈德利2號彗星自發現以來最棒的觀察機會。 由臺灣與西班牙科學家組成的觀測團隊,預計將從今年5月到12月期間,利用多架口徑1~2.2m的望遠鏡對此彗星進行長時間的觀測與研究,最終結果將與太空船所觀測的資料比對後刊於科學期刊。 資料來源:林忠義博士, 2010.05.22, KLC

Peter兄: 這樣就沒錯了 彗星應該會以這樣的軌道去跑...: 有空再研究看看囉~~

去年看大家一羅框在爭先報告鹿林的消息... 今年彗星來也不曉得為何如此的冷... : 或許跟這段長時間以來壞天氣有關 又或者跟亮度有關 出現在天空的時間點有關 或是鹿林是台灣之光 大家踴躍去追它呢?? 很值得去探討研究的話題...:

可能是nikon 180mm的鏡頭...因為和R1很像,在八、九等時就有細長尾巴,屆時尾巴應該是很細長 ,大炮反而無用武之地..
