In June, the strongest annular solar eclipse in Phnom Penh is coming.

There are many astronomical phenomena in June, and the annular eclipse, one of the most important astronomical phenomena in the whole year, is also staged in June. It will be staged on June 2 1 day. This annular eclipse is a great spectacle, which can be seen in China and should not be missed. Let's introduce it in detail through constellation knowledge.

An important astronomical phenomenon in June: the solar eclipse in Phnom Penh on June 2 1 day will usher in the summer solstice. On this day, the sun shines directly on the Tropic of Cancer, and the night in the northern hemisphere is the shortest. Therefore, we can't look at the stars as long as in winter. But there will be an annular eclipse on the solstice in summer. The annular eclipse belt passes through parts of southern China, so partial solar eclipse can be seen all over China, which is also one of the most important astronomical phenomena in a year.

In 2022, there will be two observable solar eclipses in the world, namely the annular solar eclipse on June 2 1 day and the total solar eclipse in the early morning of February 15. For China, the second total solar eclipse occurred in the far southern hemisphere, and the most obvious one was the annular eclipse on June 2 1 day.

The sun is 65.438+0.5 billion kilometers away from us, while the moon is closer to us, with a perigee of about 363,000 kilometers and an apogee of about 405,000 kilometers. If the moon is far away from us when it blocks the sun, its apparent diameter will be smaller than the sun. At this time, if there is an eclipse, the moon cannot completely block the photosphere of the sun. What we see is an annular eclipse.

On June 2 1 day, Beijing, the first day of the fifth lunar month, the apparent diameters of the moon and the sun are very close, so when the solar eclipse occurs, the sun will only present a very thin circle. We call this annular eclipse, which is very close to the total solar eclipse, the Phnom Penh solar eclipse.

The path of this annular eclipse is the annular eclipse belt, starting from Central Africa in the west, passing through Arabian Peninsula, Pakistan and India, and then entering China. The food belt passes through China, Tibet, Sichuan, Guizhou, Chongqing, Hunan, Jiangxi, Guangdong, Fujian and Taiwan Province provinces, and finally reaches the Western Pacific. This "Phnom Penh solar eclipse" is not common. The next event will not be observed until May 9, 2032, which is also in the South Atlantic.

The thinnest and most spectacular solar eclipse took place in India. The observation effect of "Phnom Penh Solar Eclipse" in China is very good. In the east of Fujian Province and Taiwan Province Province, this "ring" is already relatively wide. The eclipse zone of "Phnom Penh eclipse" is very narrow, and the eclipse time is shorter than that of conventional annular eclipse. In Ali, Tibet, the width of the circular food belt is only 20 kilometers, while in Fujian and Taiwan Province provinces, it is only 40 kilometers. In Tibet, the total eclipse lasts only 40 seconds, and the time to watch the eclipse near the eastern midline does not exceed 1 minute.

How did the annular eclipse observe such a short and spectacular astronomical phenomenon? You must arrange your trip in advance to abide by it. The annular eclipse belt passes through some parts of eastern China, and the traffic is relatively convenient, but the possibility of sunny weather this season is very low. The transportation on the Qinghai-Tibet Plateau is inconvenient, but it is more likely to be sunny. Annular eclipse appears in different places at different times. It is near noon in the west of China and near evening in the east. In order to photograph the annular eclipse, different heights of the sun have their own advantages and disadvantages. It should be noted here that during this annular eclipse, partial solar eclipse can be seen all over China. However, it should be noted that neither the annular eclipse nor the partial eclipse can directly see the sun with the eyes. We need to wear special sun observation glasses to observe the solar eclipse.
