A repeat of this event named the "Transit of Venus" is the first of its kind in the present millennium with the previous taking place in 1882. No-one alive today has witnessed such an astronomical event.

Bangladesh Astronomical Association (BAA) in collaboration with Kalabagan Krira Chakra will organise the magnificent display through Celestron 8-inch Schmidt-Cassegrain Telescope and other equipment.

"On June 8, half the world will be able to see the tiny black dot of Venus moving across the disc of the sun. Given a cloudless sky, all one needs is a sun filter to follow the display for hours with unaided eyes," says Mash hu rul Amin, Mohakash Barta's editor and BAA member.

"People who want to follow Venus' glide across the sun from their homes can do so using an exposed fresh (unused) x-ray film which is light darkish black. This big sheet must be placed over the lens of the telescope or binoculars before watching. It will prevent direct rays of the sun from causing permanent damage to the eyes. The viewfinder of the telescope should be covered as well," he added.

The venue will be equipped with a projection system with a white screen to have a wider view of the transit, Amin said.

This Venus transit will be seen after about 120 years. The times when the movement can be observed are 11:14am, 11:33am, 2:16pm, 5:01pm and the last touch -- the transit -- will be at 5:20pm on June 8, BAA officials said.
