This year's first "super moon" will appear in the night sky in the early morning of August 20. The interested public in my country can look up to the sky in the evening of the 19th to appreciate this "fat moon".
When the moon and the sun are on both sides of the earth, and the ecliptic longitudes of the moon and the sun are 180 degrees different, the moon seen from the earth is the roundest, which is called a "full moon", also known as "looking". The fourteenth, fifteenth, sixteenth or even seventeenth days of each month in the lunar calendar are all times when the full moon may appear.
Full moon time
2:26 on the 20th
Xiu Lipeng, a member of the Chinese Astronomical Society and an expert in astronomy popularization, introduced that the moon’s orbit around the earth is an ellipse. Sometimes the moon is close to the earth, sometimes far away from the earth, and The closest point is called perigee, and the opposite point is called apogee. From an astronomical point of view, a "super moon" can simply be called a "perigee full moon", that is, the full moon happens to appear near perigee. At this time, the moon looks particularly large. In this "super moon", the full moon moment occurred at 2:26 on the 20th, and the moon's perigee moment occurred at 13:00 on the 21st.
How to appreciate
It will feel bigger when you observe it in the evening
How to appreciate this year's first "super moon"? "Since the full moon occurs in the early morning, interested members of the public can observe it on the evening of the 19th. At this time, the moon has just risen from the east. Due to the ground reference, it will appear larger to the naked eye, and the color of the full moon is slightly reddish; When the moon rises to a certain height, it is difficult to distinguish this difference with the naked eye, and the color of the moon will gradually turn white or white-yellow. You don’t need professional astronomical equipment to appreciate the full moon, just like watching the meteor shower, of course. "If you use a small astronomical telescope, you can observe the bright and dark details on the moon more clearly," Xiu Lipeng said.
Super Moon
We can see it three times this year
"Super Moon" is not a rare celestial phenomenon. It can occur as few as once or twice a year and as many as three or four times a year. "There will be four 'super moons' this year and they will appear one after another. The next three will appear on September 18, October 17 and November 16 respectively. Among them, the 'super moon' on September 18 is The biggest full moon of the year," Xiu Lipeng said.
