[漢羅] Kitt Peak 望遠鏡 天頂 ê 武仙座 τ 流星雨

這毋是風暴中心，毋閣是一个值得紀念 ê 暗暝。 昨暝是 武仙座 τ 流星雨上濟彼工，這是一个毋是蓋濟、有當時仔才會出現 ê 流星雨，是 ùi 破去 ê 彗星 73P/Schwassmann-Wachmann 3 號 ê 彗星屑仔來–ê。 今年 ê 計算 kā 咱講，地球會行過 彗星殘骸 特別厚 ê 所在，按呢就會 tī 武仙座 ê 方向產生 足光 ê 流星西北雨。 毋閣實際上咱看著–ê，無算是流星西北雨，干焦是 一般 ê 流星雨。 這張相片是 kā 5 月 30 半暝 tī 美國 Arizona 州 ê Kitt Peak 國家天文台 翕–ê 超過 2.5 點鐘久 ê 影像合做一張–ê。 Tī 彼陣有翕著 19 粒武仙座 τ 流星，kah 4 粒其他 ê 流星。 毋閣你敢有法度揣著 in？ 前景較倚頭前彼个是 直徑 2.3 公尺闊 ê Bok 望遠鏡，tī 伊後壁彼个 是 直徑 4 公尺闊 ê Mayall 望遠鏡。 武仙座 τ 流星雨逐年攏有。 毋閣明年，伊應該會閣變轉去原本 較低流星率 ê 時期。 伊後一擺閣變轉來活跳期 ê 暗暝，應該愛等到 2049 年矣。

[English] Tau Herculids Meteors over Kitt Peak Telescopes

It wasn’t the storm of the century – but it was a night to remember. Last night was the peak of the Tau Herculids meteor shower, a usually modest dribble of occasional meteors originating from the disintegrating Comet 73P/Schwassmann-Wachmann 3. This year, calculations showed that the Earth might be passing through a particularly dense stream of comet debris – at best creating a storm of bright meteors streaking out from the constellation of Hercules. What actually happened fell short of a meteor storm, but could be called a decent meteor shower. Featured here is a composite image taken at Kitt Peak National Observatory in Arizona, USA accumulated over 2.5 hours very late on May 30. Over that time, 19 Tau Herculids meteors were captured, along with 4 unrelated meteors. (Can you find them?) In the near foreground is the Bok 2.3-meter Telescope with the 4.0-meter Mayall Telescope just behind it. Next year, the annual Tau Herculids are expected to return to its normal low rate, with the next active night forecast for 2049.
