February 15 marks the Lantern Festival, the year of Yin and Tiger.Surprisingly, the month of yuanxiao in the Year of the Tiger is not “15 circle”, nor “16 circle”, but “17 circle”, the roundest moment occurs at 0:56 on February 17.According to Lin Huan, a member of the Chinese Astronomical Society and an expert on astronomy science in Tianjin, the moon moves between the Earth and the sun on the first day of the Lunar calendar.Around the 15th day of the lunar calendar, when the bright side of the moon is all facing the earth, we can see the round moon, called “full moon”, also called “wang”.The time interval from “shuo” to “shuo”, or from “wang” to “wang” is called a “lunar month”, with an average of 29.53059 days.The same lunar new Day, “new Moon” may occur in the early morning, or in the morning, afternoon, or in the evening, and each “lunar month” itself has a long and short.In this way, the moon at its fullest moment “wang” can occur in the evening of the 14th lunar month at the earliest, and in the morning of the 17th lunar month at the latest.But because “new Moon” must be in the lunar new Month, “new Moon” after the average up to go through 14 days 18 hours 22 minutes is “wang”, so the most round time of the moon “Wang” to appear in the lunar 15, 16 days most.Statistics show that the “full moon” occurs most frequently on the 16th lunar month, followed by the 15th lunar month, followed by the 17th lunar month and the 14th lunar month.When is the best time to enjoy the full moon on the night of Lantern Festival?Two hours after sunset is a good time to admire the moon.”One is that the moon looks and feels really big;Second, the moon appears beautiful silver white, pleasing to the eye;Third, the moon’s level is low, which is suitable for taking beautiful photos of ‘even the moon and the landscape’.”As time passed, the moon moved due south in the sky at midnight, Lin said.At this time the moon level reached the highest all night, all is quiet, the “bright moon sky shine” also do not have a taste.”The ’17 full moon on the 15th Day’ like this year’s Lantern Festival is relatively rare. The last time it happened was on February 26, 2013, and the next time will be on March 1, 2029.But no matter when the moon is full, people with the naked eye to see the moon is basically the same, it will not affect people on the night of the Lantern Festival to enjoy the moon.”Lin said.Source: Xinhua
