On July 22nd, 2009, a spectacular total solar eclipse was observed in China. When the total solar eclipse occurs, where does the earth eat?

On the morning of July 22nd, a rare total solar eclipse once in 500 years will be staged in the sky. The total solar eclipse lasted more than 2 hours from the initial loss to the last contact, and the longest duration of the total solar eclipse was about 6 minutes. This is the longest total solar eclipse observed in China during 18 14 -2309. This is also the most populous total solar eclipse in the history of the world. Not long ago, the Chinese Astronomical Society and the National Astronomical Observatory jointly identified eight cities, including Suzhou, Nanjing Gaochun, Changzhou and Wuxi, as designated observation points for the total solar eclipse. They have prepared a colorful "astronomical feast" for astronomy enthusiasts and tourists at home and abroad. From today, this newspaper also started to register and select the activity of "witnessing the wonders of the universe and exploring the mysteries of nature-Yangzi reporter Gao Chun watched the solar eclipse" and held a "chasing the sun through the eyes" photo contest.

This solar eclipse is the longest total solar eclipse in China for nearly 500 years from 18 14 to 2309, with the longest duration of nearly 6 minutes.

China has the best observation conditions for many years.

The most wonderful total solar eclipse starts from 9: 00 am to 9: 38 am, of which Tibet is the earliest and Zhoushan is the latest.

The total solar eclipse area contains more than 40 cities.

The total lunar eclipse belt is more than 65438+100000 km long and 250 km wide. It can be seen in more than 40 cities including Chengdu, Chongqing, Wuhan, Hefei, Hangzhou, Shanghai, Nanjing (Gaochun), Wuxi, Suzhou and Changzhou.

Gao Chun set up three meeting places for simultaneous observation, which must be in place before 8: 20 am.

"According to the forecast, the probability of sunny days in Gaochun on July 22 will reach about 70%." A person from the Provincial Astronomical Society said that Nanjing is not in the total solar eclipse zone, so there is no total solar eclipse. On July 22nd, Gaochun will have three venues to observe the total solar eclipse at the same time. The main venue is located in Hubin Square. The other two venues are Nanjing Niles Instruments Co., Ltd. of Chinese Academy of Sciences and Wang Yu Island Resort. "If you want to observe this spectacle, citizens must arrive at the designated observation point before 8: 20 in the morning, because within more than 30 seconds after this time, the total solar eclipse will occur and enter the stage of' initial loss'. In the five minutes between' food' and' light', the whole Gaochun County will present a scene of night. "

It is reported that recently, some media reported that "Indian scientists will watch the solar eclipse by plane" and "India will launch a flight to watch the solar eclipse", which aroused enthusiastic response among "food fans" in Nanjing. Although some experts said that it is not feasible to watch the solar eclipse by plane due to factors such as flight speed, the reporter saw from the online forum that many Nanjing astronomy enthusiasts were already discussing the flight information on July 22, expecting to "organize a group to go to heaven day by day".

Suzhou pushes 6 viewing routes for 5 minutes, "the darkness once in a thousand years".

According to Bao Mei, director of Suzhou Observatory of Purple Mountain Observatory, Chinese Academy of Sciences, during the five-minute total lunar eclipse, the moon will completely block the sun, so Suzhou will experience five minutes of "darkness", which is the longest total lunar eclipse in Suzhou in recent 1000 years, which can be described as "once in a thousand years".

A person from Suzhou Tourism Bureau told the reporter that on July 22nd, it is estimated that nearly 10,000 overseas people and nearly 65,438+10,000 domestic astronomy enthusiasts will gather in Suzhou. By then, six "total solar eclipse" sightseeing tours will be launched for domestic and foreign astronomy enthusiasts, namely "Panmen (observation point)-Canglang Pavilion-Shantang Street-Huqiu-Guanqian Street", "Suzhou Amusement Park (observation point)-Liuyuan-Shantang Street-Xu Xun Road" and "Jinji Lake (observation point)-Kewen Center-Chongyuan Temple".

It is also introduced that a week-long total solar eclipse observation will be held in Suzhou, international year of astronomy in 2009, from July 19 to July 25. One of the seminars on "Coronal Dynamics" will be held in Suzhou from July 24 to 27, when more than 200 astronomers from all over the world will participate in the observation of the total solar eclipse on July 22, 2009. At the 2009 international year of astronomy Astronomical Science Forum held in Suzhou Convention Center on July 2 1, Chinese and foreign astronomers will disclose the latest discoveries of astronomical observation and detection.

On July 22nd, the astronomical observation operation named "1 1 1" will be launched in Suzhou and various counties and cities. In this total solar eclipse observation activity, there will be 6.5438+0 million people in Suzhou. In addition, the event organizing committee will also broadcast the total solar eclipse in real time. Experts said that in Suzhou city, as long as there is no tall building on the east side of the observation point to block the line of sight, it is suitable for observation. Residents living in high-rise buildings in the city can be immediately observed by the naked eye as long as they open the windows facing east.

The best observation time in Wuxi is from 9: 35 am to 9: 39 am on the 22nd.

The reporter learned from the relevant departments of Wuxi yesterday that Wuxi, located in the "total solar eclipse belt", is about to hold a series of popular science activities of "Observing Japanese Words and Astronomy" around the spectacle of total solar eclipse on July 22. According to relevant sources, the spectacle of the total solar eclipse on July 22nd, 2009 is rare, because it has been 434 years since the last total solar eclipse in Wuxi1May 575 10, and the next one will only appear on June 9th, 2309 after 300 years. This time in Wuxi, which is in the "total food belt", the best observation time is from 9: 35 am to 9: 39 am on July 22. It is reported that during this period, Wuxi will hold a series of popular science activities, including five sub-projects of "Four Enters and One Consultation". Among them, on Monday, July 20th, at 9: 30am-10: 30am, our city will hold an activity of "observing the sun and astronomy" in the Children's Palace, and at 2: 30pm-3: 30pm in the Houqi Street community. In addition, our city will hold three large-scale popular science consultation activities on 2 1 and 22/respectively.

An observation point in Changzhou is located in the zoo to see the reaction of elephants and monkeys.

Miss Pu, a staff member of Changzhou Association for Science and Technology, told the reporter that at about 9: 35 am on July 22, the moon was running between the sun and the earth. Under the irradiation of sunlight, the shadow of the moon will cover Changzhou, so Changzhou will go from west to east from day to night in a few minutes. It is reported that this "dark time" will last for more than 2 minutes. At present, Changzhou Association for Science and Technology, together with relevant experts and astronomy enthusiasts, has identified three best observation points in Changzhou, namely, Tianmu Lake in Liyang, Yancheng Wildlife Park in Wujin and Hongmei Park.

According to experts, animals, like humans, are about to witness this rare "historical moment". Animals also have instinctive reactions to natural wonders, and the reaction is the most obvious. For example, when there was a solar eclipse in August last year 1 Xinjiang, chickens and ducks in the local village would automatically run into the circle. It is understood that the key research of Changzhou Association for Science and Technology will focus on animals, and one of the best observation points in Changzhou happens to be located in a wildlife park. At present, Changzhou Association for Science and Technology has negotiated with the zoo that when the solar eclipse occurs, the zoo will gather a few easily controlled animals such as elephants and monkeys to observe and record their reactions during the solar eclipse.

Li Feng, a teacher in the Department of Mathematics and Physics of Jiangsu University of Technology, said that pets such as birds, goldfish and dogs raised in citizens' homes will definitely respond to the total solar eclipse. It is suggested that astronomy enthusiasts pay attention to observing the small animals around them, and observing their wonderful reactions will bring you another kind of interest. Our newspaper's "chasing the sun through the eyes" photo contest is waiting for you to participate.

The total solar eclipse on July 22nd is called "the most dazzling astronomical spectacle in the century of 2/kloc-0", and it is undoubtedly a "daily" feast for astrophotography fans in China, the host country. As the most important observation area of this total solar eclipse, Jiangsu has unique observation and shooting conditions, which will surely attract a large number of "Kuafu". Yangzi Evening News Network will hold a "Eye-catching the Sun" photo contest on the day of the total solar eclipse, and sincerely invite the wonderful works of photographers.
