1. Venus mask1. Venus maskThis mask may be useful to determine times of 2nd and 3rd contact during This mask may be useful to determine times of 2nd and 3rd contact during the transit of Venus across the Sun.the transit of Venus across the Sun.

2. Transit simulator2. Transit simulatorThis software simulate transit of Venus across the solar disc on June 8, This software simulate transit of Venus across the solar disc on June 8, 2004. The software gives a basic images about progress of an astronomical 2004. The software gives a basic images about progress of an astronomical phenomenon which nobody of us seen. Therefore may be useful as the phenomenon which nobody of us seen. Therefore may be useful as the training before observations. It shows problems with measurement of time training before observations. It shows problems with measurement of time of single contacts, too. But it is only poor imitation of the reality.of single contacts, too. But it is only poor imitation of the reality.
