                            Total Solar Eclipse on 2009 July 22 in Jindaoxia Canyon

 

Weather in Chongqing is cooperative

 

On 2009 July 22, more than 300 million people in the areas along Yangtze River in central China should have witnessed a total eclipse of the sun without pursuing it out of hometown. However, because of the bad weather, the instant of excitement was destroyed in many areas where the path of moon umbral shadow crossed. Luckily enough, Chongqing, the city of fog in China which had been considered the last city that would witness the solar eclipse surprised nearly everyone with its sunny day on Wednesday.

 

This amazing total solar eclipse lasts about five minutes in Chongqing. It is the longest one that occurs in China in almost 500 years from 1814 to 2309. It has impressed everybody who experienced the natural phenomenon, and turns those who were not so interested in astronomy into astronomical fans.

 

Dr. Steed made a right decision

 

Mr. Steed, a Doctor of astrophysics, who works in Global Science magazine, began to analyze the meteorological phenomena weeks before the day of solar eclipse, and finally made a decision that the whole staff of Global Science should go to Jindaoxia canyon, a canyon in north of Chongqing city. His experience told him it was one of the best spot to observe the solar eclipse. Dr. Steed had plenty experience of observing solar eclipse. For example, on 2008 August 1, he went to Altay, a city in the north part of Xinjiang Uygur Autonomous Region, to appreciate the total solar eclipse. He also plans to visit Egypt in the year of 2027 for another total solar eclipse.

 

Enjoy the moment

 

If the starry night sky of July 21 removed everyone’s worry, the sunny morning of July 22 assured everybody that they would definitely witness the solar eclipse. It was nearly more than 30℃ in the morning. The sunshine seemed to intend to drive away all the creatures on earth who wanted to view its fantastic show in the later moment. However, in order to enjoy the unusual spectacle better, everyone was busy of installing the cameras and telescopes without noticing the hot weather, only leaving the puppy breathing heavily with its mouth open.

 

At 8:08 the first contact appeared. Partial eclipses are very dangerous to look at because the un-eclipsed part of the sun is still very bright. So everybody wore their solar eclipse glasses to capture this moment. Since it was the first time for some ones to see the eclipse, they began to “waw---” to express their excitement. The partial eclipse became bigger and bigger and the weather went cooler and cooler. People viewed it through the telescope or the glasses every two or three minutes. Meanwhile Dr. Steed and some other guys were busy of taking photos of the eclipses. With the time elapsed, it was approaching the time of second contact. Dr. Steed told everybody to prepare to take off glasses to view the inspiring spectacle of diamond ring and baily beads.

 

Five seconds before the second contact, that was at 9:13, Dr. Steed shouted “ take off your glasses and look at the sun!” everyone did as what the doctor told and saw the last crescent was disappearing, and then they experienced the most exciting moment in the whole life---the diamond ring appeared in the sky! Suddenly the spot was engulfed in whooping, clapping and whistling. The diamond ring only lasted several seconds before the second contact. Then the total solar eclipse occurred. It was so wonderful that no words or pictures could convey adequately its beauty. The temperature was at less 10℃lower than that of the first contact and the puppy, instead of barking at the unusual pheromone, fell asleep in such a cool moment. Doctor Steed pointed at the sky with a laser point pen, saying, “Look at the star right up your head! It is the Venus. Look at the star in the lower left corner, it is the Mercury! …… ”Everyone looked where Dr. Steed pointed, and was in ecstasy. The total phase of solar eclipse was very brief. It rarely lasted 4 minutes and 50 seconds. Nevertheless, it was the most inspiring spectacles in all of nature. The sky took on an eerie twilight as the sun’s bright face was replaced by the black disk of moon. Surrounding the moon was a beautiful gossamer halo. It was the sun’s spectacular solar corona.

 

Short after the mid totality, here came the third contact. Dr. Steed advised everybody to observe the diamond ring again and baily beads but not forget to protect eyes from burning by the sun. Every one gazed at the sun without any wink. The baily beads came out! Another wave of screaming submerged the crowd. It was the most beautiful spectacle that every one ever saw. However, it only lasted two or three seconds and then disappeared. Then it was the partial eclipse again.

 

Before the fourth contact, some guys had words or pictures composed by holes on a piece of paper to utilize the pinhole imaging principle to record the moment forever.

 

At 10:30, the fourth contact happened, and the solar eclipse of 2009 July 22 in Jindaoxia Canyon came to the end.
