Cross your fingers for good weather as the planet Venus travels across the face of the sun on June 8. For a short time, Venus will come between the sun and the Earth for the first time in more than a century.

From the Earth, we will be able to see Venus' form moving across the sun's face. If the weather is good, we will be able to see this rare astronomical phenomenon from Hong Kong.

It will occur in the afternoon and early evening, between 1.12pm and 7.19pm, and last around six hours. The sun will set at about 7.09pm on that day.

The last time Venus came between the Earth and sun was 122 years ago in December, 1882. The next time it will happen will be in June, 2012.

Due to the strong sunlight, don't look directly at the sun with the naked eye nor through a telescope. Avoid looking at the planet Venus for a long time. 

A safe method is to project the sun's image onto a piece of white paper or cardboard and view the reflection.

The best places to see Venus move across the sun's face will be somewhere with an open view to the west such as Pok Fu Lam, Stanley, Lamma Island, Cheung Chau and Tai O.
