武仙座τ流星雨！?。?/p>

• 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.?

• 這不是本世紀的最大流星暴，但這是一個值得紀念的夜晚。昨晚是武仙座流星雨的高峰期，通常是偶爾有少量流星從正在解體的彗星73P/Schwassmann-Wachmann 3上落下。今年，計算表明，地球可能正通過一條密度特別大的彗星碎片流，充其量也會產生一場從武仙座劃出的明亮流星暴。事實上發(fā)生的事情并不是一場流星暴，但可以稱之為一場極好的流星雨。5月30日晚些時候，美國亞利桑那州基特峰國家天文臺（KittPeak National Observatory）拍攝了一張合成圖像，累積時間超過2.5小時。在這段時間里，共捕獲了19顆武仙座流星群內流星，以及4顆無關的流星。（你能找到他們嗎？）近前景是博克2.3米望遠鏡，后面是4.0米的梅亞爾望遠鏡。明年，預計一年一度的武仙座流星雨ZHR數(shù)量將恢復到正常的低水平，預計2049年將是下一個活躍的夜晚。（翻譯BySASU北斗星辰）
