9:00 to 9:06. Lasts 6 minutes.
On July 22, 2009, the total solar eclipse was observed in my country: the total eclipse belt passed through southeastern Tibet, northwest Yunnan, Sichuan, Chongqing, Hubei, northern Hunan, Anhui, northern Jiangxi, In southern Jiangsu and northern Zhejiang, the center line of the total eclipse belt enters the sea in Hangzhou Bay between Shanghai and Ningbo. The best observation point for this total solar eclipse is in the Pacific Ocean. The longest total eclipse duration is 6 minutes and 39 seconds. When the eclipse is at its peak, the sun's altitude above the horizon can reach 86 degrees. The eclipse minute is 1.0799. The width of the total eclipse belt here is 258.4 kilometers.

Observation conditions
From the observation conditions, the observation conditions for this total eclipse are very good. First, the total eclipse lasts for a long time, and secondly, During a total eclipse the sun is higher above the horizon. The total eclipse appeared at around 9 a.m., and the time gradually moved from west to east, and the duration of the total eclipse phase gradually lengthened. During the extreme eclipse in Jiangsu and Zhejiang, the sun's altitude above the horizon can reach about 55 degrees. In Hubei, the altitude can be between 40 and 50 degrees. In Chongqing and Sichuan, the sun's altitude can also be above 30 degrees. The complete process of a solar eclipse from initial waning to full circle can be observed throughout China's total eclipse zone. This is the only total solar eclipse observed in my country in the past 70 years. The last time it occurred was on September 21, 1941.
Meteorological conditions
From the perspective of meteorological conditions, in the middle and lower reaches of the Yangtze River in my country, around mid-June to early July every year, it is usually the "Meiyu" season, with the sky being gloomy and precipitation for days. Continuously, sometimes big and sometimes small. In late July, the Yangtze River Basin has passed the "Meiyu" season, and the probability of cloudy days is 50-60%, which means there is still a possibility of sunny days. The entire totality belt spans more than 2,000 kilometers in China. Overall, There should be sunny areas in the totality zone. The key is that for a certain person, he can only go to one observation point. It is difficult to predict the weather conditions at this location in advance. There is a whimsical way to improve the success rate. Identify several candidate observation points in advance at large distances and in multiple directions, such as Shanghai, Hefei, and Wuhan. Pay attention to the weather forecast one or two days in advance. You will be more confident about the weather at any location. You can drive thousands of kilometers to get there in one day. You don’t have to find a fixed observation point in advance, as long as you enter the totality zone. This method is a bit idealistic and may not be realistic for most people. Qualified enthusiasts can refer to it.
