>For the 7th time in Human history and last time this century, Venus will pass in front of the sun on 6 June 2012.  We are encouraging hams to join up with astronomers and observers in public places to share in this event.  It is observable worldwide except the center of the Atlantic (eastern S.America and western Africa)  Everywhere else can see parts of it.  It lasts 5+ hours and is fully visible around the Pacific Rim. In the Usa it is late afternoon on the 5th towards sunset.
>
>All previous centuries were before the discovery of radio and so sailing ships were dispatched around the globe to time the event.  From these times, the size of the Solar System could be calculated.  It took months if not years to get the data back.  Now we can do it in 0.05 seconds with Ham radio.
>
>See if you can contact hams at other Transit of Venus sites from your public observing site.  Here are the suggested calling frequencies.  We don't want contest-style pileups nor home stations.  We just want a place where similar public setups can contact like minded other public viewing sites via ham radio and make their reports.
