Where are the best observation points for a total solar eclipse, and what are the locations of the t

On July 22, 2009, the most perfect total solar eclipse once in 500 years can be seen in Xi'an, Kangding, Ya'an, Leshan, Chengdu, Zigong, Neijiang, Suining, Nanchong, Chongqing, Dazhou, Qianjiang, Yichang, Jingmen, Jingzhou, Jiangling, Shashi, Xiaogan, Xianning, Wuhan, Huanggang, Ezhou, Huangshi, Lu'an, Hefei, Anqing, Chizhou, Chaohu, Wuhu, Tongling, Huangshan, Xuanzhou, Ma'anshan, Huzhou, Changzhou, Wuxi, Suzhou, Hangzhou, Jiaxing, Shaoxing, Shanghai, Ningbo, Zhoushan and other cities. A partial solar eclipse can be seen in some areas. Yangtze River total eclipse.

Astronomical phenomena are beautiful, but we can't ignore the safety hazards while making observations. For example, due to solar eclipses, the temperature will change, the earth's magnetic field will change, and the day will suddenly darken. As a result, some animals are not adapted to their physiological habits, such as dogs, cats and other pets should be leashed to avoid livestock panic and injury incidents.

Well, come onKnowledge of horoscopesTake a look at the total solar eclipse for a list of precautions.

1. It is strictly forbidden to disguise feudalism during the period of natural phenomena, maliciously deceive the masses, and undermine the unity of the nation and the state.

2. Do not be in other dangerous places such as streets and roads, so as not to pay too much attention to the danger of life caused by the eclipse, and pay attention to safety when you are on the balcony to avoid falling downstairs.

3. Due to the temperature caused by the solar eclipse, the earth's magnetic field changes, and the day is darkened. As a result, some animals are not adapted to their physiological habits, such as dogs, cats and other pets should be leashed to avoid livestock panic and injury incidents.

Observe a total solar eclipse and do not observe it directly.

Medical experts point out that "solar retinitis", in which the macula of the retina is burned due to ultraviolet and infrared rays that look directly at the sun for a long time, is almost impossible. The macula of the retina is the most sensitive part of the retina, which allows light to be concentrated and the image clear. Once burned, the retinal macula will never recover.

You may not feel it when you get burned, but you will react a few hours later, and in severe cases, you will lose sight. For this reason, the first thing to note during a total solar eclipse is that you should never look directly at the sun with the naked eye or any optical device (such as a telescope, etc.)!

This is not just a suggestion, but a very serious warning. How can we avoid some accidents? Here are a few ways to do it.

1) Quick and easy methods of observation.

In fact, the recommended practice is to use just two blank sheets of paper. One piece of white cardboard is used as a screen, and a pinhole is poked in the other cardboard, holding the pinhole cardboard up as far away from the screen cardboard as possible. The farther apart the two cardboards, the larger the image formed.

Of course, there is an easier way, you only need the help of your own hands, raise your hands up, and the fingers are perpendicular to each other, cross and overlap, so that the hands form a net with many small holes, which can be used as simple imaging holes.

2) Buy observation glasses or lenses.

Protective glasses require a special pair of glasses. There are glasses with this special sun observation protection lens on the market, ** about 5 yuan.

You can't make your own goggles, it's very dangerous.

3) Take a basin of water (a small cup is fine) and drip a relatively large amount of black ink into the water, which can be observed in the water during a solar eclipse. (Planar Mirror Imaging).

The annular solar eclipse in June 2020 will be visible across the country, and a partial solar eclipse will be visible in some areas.

A solar eclipse is simply an astronomical phenomenon that means that when the Moon moves to the shadowed part of the Earth, the area between the Moon and the Earth is blocked by the Earth because of sunlight, and the Moon disappears. The sun, the earth, and the moon are in the same straight line. During a solar eclipse, the sun suddenly dims, which affects the geomagnetism.

The effects of a lunar eclipse are more significant as compared to a solar eclipse. Because the moon itself does not emit light, all the livelihoods of the earth depend on the sun, and it is not the moon that dominates the geophysical phenomena of the sun.
