A solar eclipse occurs when the moon crosses between the Earth and the sun. The moon casts a shadow on the Earth's surface and obscures the sun.
People must not look directly at the sun with the naked eye or through a telescope. They also should avoid observing the eclipse for a prolonged period. A safer method is to project the sun's image through a pinhole onto a piece of white paper or cardboard and view the projection. For details click here.
The next solar eclipse observable in Hong Kong will occur on August 1 next year. It will be a total eclipse, but will only be visible as a partial eclipse in Hong Kong.
