The annular eclipse will begin at about 10:29 on the 26th Beijing time and end at about 16:05, after more than five hours. The annular eclipse zone will start from the Middle East, pass through the southern tip of India and Sri Lanka, enter Indonesia, Singapore, Malaysia and other countries in Southeast Asia, and finally end in the Western Pacific.
The average width of the annular eclipse zone is about 115 kilometers, and the longest observation time can be about 3 minutes and 40 seconds. People in the annular eclipse zone can enjoy the annular eclipse, while outside the annular eclipse zone, only partial eclipses can be observed.
Kou Wen, senior engineer of Beijing Planetarium, told reporters that during the annular eclipse the next day, different degrees of partial solar eclipses can be observed throughout China, and the more southward the 'eclipse score' (the proportion of the moon covering the sun's diameter) is, the more the sun is' eaten '. For example, the' eclipse score 'of some cities in Hainan can reach more than 0.5, while the' eclipse score 'of Beijing is only 0.15.
In Beijing, the initial loss occurred at 12:53, the eclipse occurred at 13:47 and the reunion occurred at 14:38, that is, the whole partial solar eclipse will last nearly two hours.
What is the difference between an annular eclipse and a total solar eclipse? Cowen said that a solar eclipse is an astronomical phenomenon formed when the moon moves between the earth and the sun and blocks part of the sun. A solar eclipse occurs when the moon is close to the earth. The moon looks larger than the sun. Completely covering the sun is a total solar eclipse. On the contrary, a solar eclipse occurs when the moon is far away from the earth. The moon looks smaller than the sun and can only cover the central part of the sun, leaving a 'golden ring' on the edge, which is an annular solar eclipse.
How do interested people observe? Kou Wen said that you can't look directly at the partial solar eclipse. You need to pay attention to protecting your eyes. You'd better wear professional eclipse glasses to prevent the light from hurting your eyes. " Traditional sunglasses or X-ray films can not effectively block the damage of sunlight. When shooting a partial solar eclipse, a dimming device should also be installed in front of the lens. "
Although China is not in the annular eclipse belt this time, astronomy lovers need not regret it. Kou Wen said that China will have another annular eclipse on June 21, 2020. " Those who are interested in observing and shooting can take advantage of this opportunity to try and prepare for the annular solar eclipse next year. "
