On June 8th, 2004 Venus will pass the Sun's disc - an event which looks slightly different when observed from different locations on Earth.
|Koblenz, 8.22 UT||Windhoek, 8.22 UT|
The differences are smaller than the apparent radius of Venus and you can recognize them only by exact measurements or by combinating simultaneously taken pictures:
Therefore, an international cooperation between schools, amateur astronomers and universities has prepared careful observations of the transit.
The main goals of the project are
The basic ideas and intentions of this project a described in detail in a paper which can, although not yet ready, be downloaded in an English version and in a German version.
|Daylight side of the Earth when Venus enters the Sun: From this part of the world the 1rst and 2nd contact can be observed.||Daylight side of the Earth when Venus leaves the Sun: From this part of the world the 3rd and 4th contact can be observed.|
|5.20 UT||11.30 UT|
|Project 1:||Measuring the radius of Venus' orbit|
|Project 2:||Determining of the own geographical coordinates and the projected distance of different observers|
|Project 3:||Determining the radius of the Earth|
|Project 4:||Measuring the angular radius of the Sun|
|Project 5:||Exercises in photographing the Sun and
exact position measurements on the Sun's disc (Sunspots)
|Project 6:||The Transit of Mercury on May 7th, 2003|
The first problem for preparation can be found here!
Besides there are several other sites dealing with the transit of 2004 or, respectively, with transits in general. We have collected those of the most interesting of them and describe them shortly in a pdf-document. Looking at one of those sites you will find a lot of additional information and links.
The participants of our project have been pupils, teachers, amateur astronomers, university teachers and so on all over the world.
