When is the partial solar eclipse today?

There will be an annular solar eclipse in the sky today, but in our country, we can watch the complete annular solar eclipse, but we can watch the partial solar eclipse. So when is the partial solar eclipse today? What time is it now? What should we pay attention to when observing solar eclipse? The following is revealed by constellation knowledge!

When is the partial solar eclipse today? 19 The only total solar eclipse in 20 19 will be staged on February 26th, and a partial solar eclipse can be observed in China. The annular solar eclipse will start at 10: 29: 50 Beijing time on 26th and end at 16: 05: 43, lasting more than five hours. Astronomical experts said that during this annular eclipse, partial solar eclipse can be observed all over China, and the farther south the eclipse (the ratio of the moon covering the diameter of the sun) is, the greater it is. According to experts, around 10: 56, the penumbra of the moon entered the Ali region of Tibet, and then it swept across China to the northeast. Different degrees of partial solar eclipse can be seen in China, among which Hainan has the largest food score of 0.499; Mohe has the smallest food score, which is 0.02 1. After 15: 37, the penumbra of the moon left China from Hainan Province. For China, it can be seen that the solar eclipse lasted more than four hours. It is understood that when the sun, the moon and the earth are in a straight line and the moon is between them, an eclipse will occur. Eclipses are divided into total solar eclipse, annular solar eclipse and partial solar eclipse. If the distance to the moon is far from the earth, and the sun is close to the earth, and the apparent circle of the moon is too small to completely cover the sun, an annular eclipse will occur. When the annular eclipse occurred, the sun in the sky turned into a ring, shining like a gold ring.

Why can China only see partial solar eclipse this time? It is reported that the reason is that the whole of China is not within the scope of the pseudoumbra of this annular eclipse, but within the penumbra. The surface of the earth is very large, and the range of man-made objects projected by the moon on the earth is limited. Or to put it another way, during this annular eclipse, we are not completely in line with the moon and the sun, but somewhat different, so we can only see that part of the sun is blocked, that is, the phenomenon of partial solar eclipse. According to astronomers' prediction, on the morning of February 26th 10: 29, an annular solar eclipse will begin in the Middle East. The western part of China will see the partial solar eclipse at 10: 56 in the morning and will leave the southern part of China at 3: 37 in the afternoon. Although the partial solar eclipse is not as spectacular as the total solar eclipse and the annular solar eclipse, it is also wonderful.

Precautions 1. Don't watch it in dangerous places such as streets and roads, so as not to pay too much attention to the life danger caused by solar eclipse. Pay attention to safety when watching from the balcony, so as not to fall from the building. 2. Due to the solar eclipse, the temperature changes, the earth's magnetic field changes, and the daytime becomes dark. Some animals are not adapted to their physiological habits, such as dogs, cats and other pets. They should be tied up to avoid animal panic and personal injury.

Do not directly observe the total solar eclipse. Medical experts point out that "solar retinitis" which burns the macula of retina for a long time due to its ultraviolet rays and infrared rays is almost incurable. Macula is the most sensitive part of retina, which makes light converge and makes the image clear. Once burned, the macula can never be recovered. You may not feel when you are burned, but you will react after a few hours, and in severe cases you will be blind. To this end, when watching the total solar eclipse, we should first pay attention to one thing: never look directly at the sun with the naked eye or any optical equipment (such as telescopes)! This is not only a suggestion, but also a very serious warning.
