It is said that there will be a total solar eclipse on the 22nd. Where can I see it?

The total solar eclipse of the Yangtze River in 2009 refers to the spectacular total solar eclipse that occurred in the Yangtze River valley of Chinese mainland on July 22nd, 2009. At 8: 00 am on July 22nd (the first day of the sixth lunar month), in the middle and lower reaches of the Yangtze River in China, Chengdu, Chongqing, Wuhan, Hefei, Hangzhou, Shanghai and many other big cities will see the most important and longest-lasting total solar eclipse in this century. The total solar eclipse lasts for five or six minutes in many places. At that time, the umbra of the moon will travel eastward along the Yangtze River, sweeping through many important towns on both sides of the middle and lower reaches of the Yangtze River, and the number of witnesses will be unprecedented. This will be a veritable "09 solar eclipse"! The longest duration of the total solar eclipse can reach about 6 minutes. More importantly, the area covered by the eclipse belt is one of the most densely populated areas in China, and the number of people directly watching the total solar eclipse may be the highest in history. This total solar eclipse may be the most perfect one in the last hundred years, and it took the longest time between 199 1 and 2 132.

The best observation point of this total solar eclipse is on the sea east of Shanghai, which is far from Shanghai. On land, the best are Anji and Jiaxing in Hangzhou, Zhejiang. The longest observation time is in Yangshan Port in the south of Shanghai, where you can see a total solar eclipse for six minutes.

The best observation point of the total solar eclipse lasts for more than 5 minutes, but in other areas, as long as it is on the center line of the total solar eclipse, the total solar eclipse lasts for 4-5 minutes, which makes no difference to our general fans. Please see here for the time difference;

The best observation points for the total solar eclipse are Anji and Jiaxing in Hangzhou, Zhejiang Province, where it often rains in July, but it is not the best. I'd rather go to Wuhan, a city where the total solar eclipse lasts for 4 minutes, because the chance of rain there is much less. So some people will choose to go to Wuhan to watch the total solar eclipse;

So remind friends who want to go to East China to see the total solar eclipse. In the middle and late July, there is a greater chance of rainfall in East China. Watch the weather before you go and be ready to move at any time. Of course, you like to watch the total solar eclipse through dark clouds, and no one objects. My initial plan is to go to East China to see the total solar eclipse, first to Hangzhou, and then to Jiaxing or Huangshan as appropriate.

Matters needing attention in observing total solar eclipse

Observing the sun is very dangerous because it emits strong visible light, infrared light and ultraviolet light. Ultraviolet rays not only burn the skin, but also cause rapid damage to the retina of the eyes. As long as human eyes look directly at the sun for a few seconds, it may cause permanent damage or even blindness. If the sun is observed through a telescope without proper dimming equipment, the consequences will be even more unimaginable. Partial solar eclipse and annular solar eclipse can't be watched without special safety measures. In the partial eclipse stage of the total solar eclipse, even if the surface of the sun is covered by the moon for 99%, the photosphere formed by the new moon will still cause harm to the eyes. Don't try to observe the sun with the naked eye at any stage of partial or annular solar eclipse.

Here are some scientific observation methods for you:

Ink observation method (but this method is not recommended because of its low dimming rate and easy eye injury)

You can take a basin of water, add ink, and see the sun through the reflection of water.

Pinhole projection method

Make use of two boards, dig a small hole in one board, and let the sunlight pass through this small hole and project onto the other board.

telescope projection method

Don't shake your hands, or the shadow of the sun will run back and forth. Never look directly at the sun with a telescope. If you look at the sun directly with a telescope, you must use a filter.

note:

Never use the so-called "sun card" or "eclipse card" provided by informal institutions.
