Transit of Venus, Centenary of Vitamins

6 June 2012 last chance to see: Transit of Venus

Only six transits of Venus are known to have been observed by humans in 1639, 1761, 1769, 1874, 1882 2004.
[I reckon Mayans must have used a pinhole in a leaf... they knew Venus better than Spaniards did]

..Venus..round black spot with a diameter.. 1/32nd of the sun...
..entire transit (all four contacts) is visible from .. New Zealand.
