Have you been an eye witness?
The transit was well observable in Holland due to the excellent wheather. The first video's and photos are already placed at our image gallery. Photo's of amateur astronomers are also available here. If you want your transit photograph(s) to be placed on our site, please do not hesitate to mail them to webmaster@venusvoordezon.nl.
Solar distance 
Thousands of observers all over the world have timed the Venus Transit and combined their observations with those of others over the internet to calculate the Solar distance together. This 'democratic' calculation of the Atronomic Unit turns out to be much more accurate than the best results of prefessional astronomers in the 19th century. 'From this, it can be concluded that amateurs and schoolchildren are capable to perform very accurate astronomic measurements', according to Robert Wielinga of the meseum observatory Sonnenborg Utrecht.
Venus athmosphere
On this g band DOT picture, one can see the Venus atmosphere, lit by the sun light from the back. This way the Russian atronomer Mikhail Lomonósov concluded in 1761 Venus had to have an atmosphere.
