Venus transit campaign over the Pacific limb in 2012 (AU by Venus)

in the Pacific limb on June 6 by multi-point observations

On 6 June we have a Venus transit in front of the Sun. Simultaneous observations over the Pacific Ocean will give a basic data to estimate 1 AU, which is the distance between Earth and the Sun. It is basically the same procedure to estimate 1 AU as the leading scientific observations only 100-200 years ago.
