天文专家介绍,宝瓶座伊塔流星雨6日迎来极大,每小时将有数十颗流星划过夜空。届时,如果天气晴好,我国各地公众均有望目睹到“长尾巴”流星。

宝瓶座伊塔流星雨的母体彗星是大名鼎鼎的哈雷彗星,每年都会为公众带来两场较大的流星雨,一场就是5月初的宝瓶座伊塔流星雨,另一场是10月中下旬的猎户座流星雨。

天文教育专家赵之珩介绍说,整个上半年活跃的大流量流星雨都很少,年初的象限仪流星雨之后,真正“拿得出手”的要数5月上旬的宝瓶座伊塔流星雨了。

据了解,宝瓶座伊塔流星雨群内流星属于快速流星,且亮流星多,很多流星都有余迹,还是很值得天文爱好者观测的。天文预报显示,今年的宝瓶座伊塔流星雨极大可能出现在北京时间5月6日22时。

“观测宝瓶座伊塔流星雨,南半球比北半球有利,并且观测时间比北半球长。宝瓶座流星雨上半夜是看不到的,应在下半夜观测。在南半球,可在天亮前4小时左右投入观测;而在北半球,则应在天亮前2小时投入观测。对于我国各地的观测者来说,6日和7日是较为理想的观测时段,且无月光干扰。”赵之珩提醒说。

宝瓶座伊塔流星雨6日极大 公众可赏"长尾巴"流星
