Summary of astronomical phenomena during the Spring Festival in February, 20021year. At this time, there are more planets in phase.

In February this year, we can also see many astronomical phenomena. Because it happens to be the Spring Festival, many friends will have more time. You can choose places with less light pollution to see these astronomical phenomena.

Astronomical phenomena in February 20021year

Around the Spring Festival holiday, there were many planetary eclipses. February 10, 14, 17, 19, Saturn, Neptune, Uranus and Mars will meet.

Judging from the order of the first performances, the first one is Saturn's full moon, so it can be watched at the dawn of February 10, while the full moon of February 19 is suitable for watching after sunset to midnight.

Shu Qi urges spring, and Samsung sends blessings. February, 20021year, the common protagonist in the night sky was "big v"-five planets, meteor shower, etc. Almost all faded out of the starry stage. "Winter Triangle" and Orion become the absolute protagonists in the night sky, making the sky of "three bright stars" more conspicuous and the peaceful atmosphere of "New Year is coming" more intense.

Venus, the brightest star in the night sky, is the morning star in February and appears in the eastern sky before dawn. However, its altitude is very low and the observation conditions are not good. Mercury will set on February 8, that is, it will rise and fall with the sun, and it will be difficult to see for the whole month. Throughout February, Jupiter and Saturn were also submerged by the sun and could not be seen. Only Mars is speaking for the earth. After nightfall, we can see the red planet hanging high in the southern night sky, close to the zenith. Its condensation time is basically in the early morning of the next day, and the observation conditions are good in the first half of the night.

The auspicious three treasures represent Fu Lushou.

Sirius is the most striking star in the night sky in February 20021year. It is the brightest star in the whole day. After dark, it shines blue and white in the southeast sky. It forms an equilateral triangle with two bright stars in the north, which is the famous "winter triangle". The reddish one in the northwest corner is named Betelgeuse, which is the "left shoulder" of Orion. Below it is the waist of Orion, and there are three other bright stars with almost the same brightness, which are very eye-catching, even in a big city like Beijing, you can see them on a full moon night. In the ancient star official system of China, Orion's celestial region belonged to Betelgeuse. "God" means "three", and the three stars on the "belt" are the constellations of Betelgeuse, which ancient astronomers called "Shi Heng". People in China often regard them as three stars representing happiness, wealth and longevity.

People often say that "three stars are shining, and the new year is coming", which means that when you see these three stars in the southern sky shortly after dark, the new year is coming. 202 1 February 1 1 New Year's Eve, about two and a half hours after sunset, Samsung shines due south. If observed in Beijing, it will be around 20:25.

When the moon shines, there is much to see.

The moon runs once a month with the starry sky as the background, often close to other bright celestial bodies, resulting in various "closed moon" phenomena.

On February 19, Mars and the Moon will be staged. On this day, the moon phase is the first round, and the orange Mars is more than 4 degrees above the right side of the moon, in contrast to the silver moonlight. On the evening of February 20th, Xianyue came to Aldebaran, the brightest star in Taurus, and merged with Aldebaran, about 5 degrees apart. On that day, the brightness of Aldebaran was similar to that of Mars, and the height was also very close. Both can be described as "temporarily bright", but Mars is redder.

On the evening of February 26th, Lantern Festival, there will be "Fourteenth Meeting of Xuanyuan". Xuanyuan XIV is the brightest star in Leo, which belongs to the "Xuanyuan" star official in China's traditional star official system. But as Cao Cao wrote in "Short Songs", "There are few moon stars, and black magpies fly south." When the full moon is in the sky, it is not easy to see the stars next to it with the naked eye. One or two hours after sunset that night, when the height of the moon was less than 40 degrees, it was quite difficult to find Xuanyuan XIV, which was 4.6 degrees to the south. It is best to use binoculars. Then more than two hours later, the moon and Xuanyuan 14 rose into the sky, and the atmospheric extinction weakened, which was visible to the naked eye.

The moon meets the blue.

This year's Lantern Festival, the starry sky will also provide us with "welfare": the moon will cover Xuanyuan XIII (the star is in Leo, with a brightness of 3.5). ) In the area south of China and east of Lhasa, the bright star Leo can be seen disappearing from the left side of the moon and reappearing from the right side after being blocked by the moon for a few minutes. The specific occultation time varies from place to place, generally concentrated between 20: 00 and 22: 00 that night, which is the prime time to enjoy the moon. In southwest areas such as Kunming, Lhasa and Nanning, occultation began earlier. For example, in Kunming, the occultation begins at 20:05 and ends at 2 1: 10. Occlusion in the eastern region started and ended late, such as 20:36 in Shanghai, and the ending time was 2 1:27. Taipei starts at 20:26 and ends at 2 1:4 1.

Because the full moon is very bright, the nearby stars will be submerged by moonlight, and we need an astronomical telescope to see it. It really takes a lot of effort to realize the benefits of this Lantern Festival.

During the Spring Festival, there are many planets in conjunction with the moon.

What is "the moon and planets"? Hu Hu, director of the Science Popularization Department of Purple Mountain Observatory of China Academy of Sciences, said that according to the definition of China astronomical calendar, the so-called moon-moon conjunction refers to the moment when the center of the moon and the planet are at the same right ascension. The eight planets in the solar system have a "full moon" phenomenon about once a month.

Visually, when the moon is close, it is also the time when the planet is close to the moon. If the equatorial latitudes of the moon and the planet are close when the moon is closed, the moon may cover the planet in some parts of the earth.

In addition to the combination of planets and the moon, there are stars and the moon, planets and stars, planets and planets. The word "he" in these celestial phenomena has the same meaning, indicating that the right ascension of celestial bodies related to the center of the earth is the same.

Similar to the combination of the planet and the moon, there is another term that everyone often mentions, that is, the planet accompanies the moon. However, accompanying the moon is not an astronomical term, but a common name, which generally refers to the phenomenon that planets and the moon look closer together. When the closing dates of several planets are close, it is easy to see many satellites accompanying the moon at night.

Specifically, several planets meet the moon in February, and Saturn and Mars meet the moon, which is more suitable for viewing. Hu reminded that the combination of the moon, sun and planets can be seen at dawn on 10, while the combination of Mars on 19 is suitable for viewing from sunset to midnight.
