A Rare, Spectacular Astronomical Sight - Double Sun
Recently, the media has reported unusual phenomena in China, including mirages and UFO sightings. According to news report published on December 16, 2002, a marvelous astronomical sight appeared beside the Jiuzhan River, Harbin at dusk. As the fiery red Sun was setting in the west, another round object as bright as the Sun appeared in the sky. According to eyewitness descriptions, at 3:45 PM on that day, people were enjoying the beautiful scene of the setting Sun by the riverside when they suddenly saw a "White Sun" positioned sideways above the setting Sun.
This "White Sun" was one size smaller than the setting Sun and bright white in color. At the beginning, people thought it was the moon. But it was positioned so close to the Sun and shone with such an unusual light that people did not know what to make of it. A while later a crescent-shaped moon appeared on the south side of the sky. So the white object was not the moon as people had first thought. At 3:48 PM, the upper half of the "White Sun" that had been hidden by the cloud layer revealed itself in the shape of a semicircle. People saw it clearly in the sky for the next seven minutes. At 3:55 PM, as the Sun set completely, the "White Sun" was blocked by the red clouds and vanished.
The same thing was observed for the next eight days. According to experts in the field, such a phenomenon is unusual. They were not able to offer any persuasive explanation to the reason why this sighting occurred.The above is one form of the "Double Sun." Another form of the "Double Sun," the more common one, takes the shape of a concentric ring with the Sun in the middle.
A news article published in the "Peninsula Metropolitan Newspaper" (a local newspaper in the city of Qingdao) on May 25, 2002 stated, "Around 10 AM on May 24th, a magnificent and marvelous sight suddenly appeared over the sky of the city: A colorful and dazzling circle of light emerged around the Sun. From the elevated view of a tall building, one could see an unusual circle of light with the color red on the inner side of the ring and the color yellow on the outer side of the ring. It was extremely eye-catching under the clear sky.
About half an hour later, a second colorful, dazzling circle of light appeared around the Sun. It was even more gorgeous than the first one. The circle of light gradually faded and disappeared completely around noon." Around the same time, on May 24th at 12:30 PM, a colorful circle of light appeared above the sky of Dongying City, Shandong Province. It encircled the Sun until 2:30 PM when it vanished.
Lhasa, Tibet sits 3000 meters above sea level. It is known as the "City of Sunlight." The sky there is consistently clean and clear. The "Double Sun" phenomenon has also appeared there. According to a Chinese News Agency report, on the morning of May 1, 2002, tens of thousands of city residents saw two giant colorful concentric rings around the bright Sun. The most readily observable color of the rings was orange, the next one was yellow, then green, blue, and white. The two rings were in a perfectly circular shape, just like that drawn by a compass [4]. The diameter of the inner ring was about twenty times that of the sun.
The area between the edge of the sun and the inner ring was pitch black, which made the Sun in the center stand out even more. The diameter of the outer ring was about forty times that of the sun. The area inside of the outer ring was dark blue. These two rings were so large that they looked like a hat covering the entire city of Lhasa. Several veteran reporters and staff members of the Chinese news agency who have worked in Tibet for many years said that it was the first time they had seen such a magnificent celestial phenomenon. Some people thought what had happened was either an unusual sun ring or aureole. The occurrences of sun rings or aureole are usually related to moisture in the upper atmosphere, high ground temperature, and excessively strong solar light. However, the reason why two such large rings appeared around the Sun still needs further analysis.
Similar phenomena have also happened in other major cities in China, such as Beijing, Guangzhou and Kunming. An even more rare phenomenon related to the Sun is when several suns are seen shining in the sky. Such phenomena happened in ancient times. The most well-known one took place during the reign of Emperor Yao. It is recorded in many ancient history books that ten suns were seen appearing in the sky at the same time. In China, this kind of unusual celestial phenomenon has happened again.
