Eclipse: Only visible when the sky is clear

On March 19, the weather made many people disappointed because they could not see the solar eclipse . In Hanoi, the sky was cloudy. In Ho Chi Minh City, it is sunny but it is cloudy.

According to scientists' forecast, on March 19, a partial eclipse can be observed in Hanoi and Ho Chi Minh City. However, according to Mr. Dang Vu Tuan Son, Vietnam Astronomical Society, in Hanoi, although there are still many people curious, want to observe this astronomical phenomenon, but all must be pity, ignore.

The simple reason is that, during the 3 days before the eclipse, Hanoi was murky and rainy. On March 19, the day of the solar eclipse, it was not raining but cloudy and sunny.

Meanwhile, Dr. Nguyen Van Khai, a physicist who used to have a thesis on astronomy and is currently the Director of Hanoi's Center for Energy Efficiency and Solution of Chemical and Electrochemical Savings, is also not surprised. when in Ho Chi Minh City, I also couldn't see the solar eclipse and made many people disappointed. He said he was working in the south and according to his observations, the southern sky, in Binh Thuan and Ho Chi Minh City, although sunny but also cloudy on the morning of March 19.

According to Dr. Khai, can see clearly the solar eclipse with clear sky conditions.

In the case of cloudy, blind weather, ie there is a lot of water vapor in the air, due to light scattering and refraction, it is difficult to observe an eclipse. It is best to only see a small, slightly distorted halo and it is difficult to impress the observer if it is an "eclipse"!

On the other hand, during this solar eclipse, the Moon obscures only a small part of the Sun, so the difference is not large, so people did not see the solar eclipse.

Dr. Nguyen Van Khai also said that when announcing information about solar eclipses, scientists or specialized agencies should clearly announce the location and coordinates that can observe the solar eclipse.

This is also a good method of education for students, students and those interested in astronomy, an area in our country today, the education and propagation of knowledge is still very sketchy.
