[貼圖] 英仙座流星雨

Perseid in the Light

影像版權與提供: Jimmy Westlake (Colorado Mountain College)
Explanation:
     Dark skies are favored for viewing meteor showers -- so many are pessimistic about this year's Perseids. While the Perseid meteor shower is scheduled to peak this weekend, bright light from an almost full Moon will also flood the night and mask the majority of relatively faint meteors. Still, skygazing in the evening before the Moon rises (before about 10 PM local time) could reveal spectacular earthgrazing meteors. Persisting even later into the moonlit night can reward northern hemisphere watchers looking for occasional Perseid fireballs. In fact, astronomer Jimmy Westlake imaged this bright Perseid meteor despite the combination of moonlight and auroral glow over Colorado skies in August of 2000.
說明:
      黑暗的天空 中是最好觀測流星雨的時機，雖然很多人並不看好這次的英仙座流星雨。 這個禮拜正是英仙座流星雨處於尖峰的時刻，但剛好滿月，所以瀰漫的月光掩蓋黯淡的流星。 對於地球上的流星雨愛好者，最好的觀測時間是在月亮升起之前，也就是當地時間晚上10點前。 月亮升起之後，那些仍然堅持繼續觀測的人員能夠看到偶而的流星火球， 事實上，天文學家(Jimmy Westlake)紀錄熾亮的英仙座流星雨，雖然結合了月光及極光，在西元2000年8月科羅拉多的夜空。
