“曰本XXXX16”紫金山天文台:曰本XXXX16狮子座流星雨派发初冬“浪漫礼物”

  中新曰本XXXX16社南京11月15日电 (记者 曰本XXXX16徐珊珊)据中国科学院紫金山天文台15日消息,有着“流星雨之王”美誉的狮子座流星雨将于本月17日晚至18日凌晨迎来极大。届时每小时预计会有10颗左右的流星自夜空洒落,派发初冬“浪漫礼物”。

  狮子座流星雨的母体是坦普尔-塔特尔彗星,这颗彗星围绕太阳运行一周的时间约为33.3年。因此每隔33年左右,狮子座流星雨的流量就会明显上升,甚至会出现“流星暴雨”。

  中国科学院紫金山天文台科普主管王科超介绍,作为周期性爆发流星雨,狮子座流星雨上一次大规模爆发是在2001年。当年,狮子座流星雨迎来“高光时刻”,极大时每小时的流星数量高达几千颗,非常壮观,给观看者留下了极为深刻的印象。

  今年狮子座流星雨规模如何?王科超表示,近些年狮子座流星雨的表现十分“低调”,今年也没有爆发的预期。本次狮子座流星雨极大期间接近满月,受到月光影响,可观测的流星数量将进一步减少,只能寄希望于火流星的出现。

  王科超提醒,狮子座流星雨极大期间,其辐射点会在午夜之后升到合适的高度,喜欢流星雨的公众可在天亮之前的后半夜进行观测。虽然流量不大,但如果运气好的话,还是会有机会看到明亮的火流星高速掠过夜空,依然值得期待。

  “欣赏狮子座流星雨,直接用肉眼看即可。观测时尽量避开月光,可选择一个视野开阔、没有光污染的区域。需要注意的是,眼下正值初冬时节,夜晚气温较低,观测时一定要做好保暖工作。”王科超说。(完)
