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.
