202 1 Longtou Huangli

2 1 Welcome "February 2nd, the dragon looks up". Astronomical science experts said that this year's "Dragon Head Up" happened around 10 at night. What does "the dragon looks up" mean? When can I see the "Dragon Heads Up"?

Wang Kechao, director of science popularization at Purple Mountain Observatory of China Academy of Sciences, said that in order to observe astronomical phenomena, the ancient people in China divided the stars in the equatorial and ecliptic regions of the celestial sphere into 28 star groups, which were called 28 hostages. In the twenty-eight lodgings, every seven lodgings are a group: black dragon in the east, suzaku in the south, white tiger in the west and Xuanwu in the north.

"The Oriental Black Dragon consists of seven nights: horn, kang, ground, room, heart, tail and dustpan, which vividly outlines the image of the dragon: horn is the head of the dragon, kang is the neck of the dragon, the elder is the chest of the dragon, the room is the abdomen of the dragon, the heart is the body of the dragon, and the tail and jump together represent the tail of the dragon. "Wang Kechao said that" lóng heads up "reflects the image of the horned toad rising from the eastern horizon, just like a" dragon head "lifted.

About 2000 years ago, the ancients in China saw "On February 2nd, the dragon looked up" shortly after sunset. Due to precession, people usually don't see the "Rise of the Dragon" until 8: 00 or 9: 00 on the second day of the second lunar month.

This year, I watched Dragon Head Up relatively late, about 10 in the evening. Wang Kechao explained that in addition to the influence of precession of years, the time when the same starry sky appears in a day is also related to the Gregorian calendar date. The same star rises about 4 minutes earlier than the day before. This year, the second day of the second lunar month corresponds to February 2 1 day of the Gregorian calendar, and the "Dragon Rise" time on this day is more than 1 hour later than the "Dragon Rise on February 2" on March 202 1 day.

In the nearly two months after the second day of the second lunar month, the public can see the sight of "the dragon rising from the horizon" at different time periods in the evening. It takes about 6 hours for the whole black dragon to rise from the horizon. From mid-July to mid-June in Gregorian calendar 10, gūng people can see the "dragon shape" of the black dragon in the night sky after nightfall.
