[Commentary] On May 6, the reporter learned from the Purple Mountain Observatory of the Chinese Academy of Sciences that the "gift" from Comet Halley-Aquarius η meteor shower ushered in on the 6th. At that time, the meteor with a "long tail" will be tens per hour A meteor crossed the sky and dressed up Tianyu.
【Explanation】 According to Hu Fanghao, an engineer from the Science Department of the Purple Mountain Observatory of the Chinese Academy of Sciences, in early May each year is the season of the η meteor shower shining in the night sky. Among the comet family, Comet Halley is a well-known member. Because its radiation point falls in Aquarius, Hence the name "Aquarius meteor shower".

The η meteor shower in Aquarius will usher in its maximum period in the early morning of May 6. The parent comet of the meteor shower in Aquarius is the very famous Comet Halley. Halley's comet will not only produce an η meteor shower, but also another Orion meteor shower in October.
[Explanation] The meteor occurrence rate per hour at the "high light moment" is generally dozens, which is not very large. But compared with other meteor showers, the best observation time is longer, and there are more bright meteors. Many meteors will drag their long tails and have a higher degree of appreciation.

The η meteor shower in Aquarius is characterized by more bright stars, and some (meteoroids) will also drag a long tail, some people also call it "long-tailed meteor". When observing meteor showers, you should choose a place that is less affected (small) by city lights to observe. If you observe in the wild, you need to pay attention to safety.

The "super moon" is actually the full moon that occurs near the perigee. We know that the moon moves around the earth in an elliptical orbit. One point is closest to the earth, and the other is the farthest from the earth. The corresponding is the perigee or apogee. , The full moon near the perigee, we call it "super moon", because this time we will look bigger than usual full moon.
