2012 Venus Transit and Annular Eclipse
April 22, 2012 5 Comments
I’m gearing up for two big eminent celestial events. On May 20th I’ll be near Page Arizona observing an annular eclipse of the Sun and on June 5th, weather permitting, I’ll be in St. Louis watching Venus creep on the disc of the Sun for the last time in my lifetime.
Eclipses and transits are spectacular events for amateur astronomers and innocent bystanders. Of the two eclipses offer the greater spectacle. In fact, for sheer unbridled awesomeness, it’s hard to beat a total eclipse of the Sun! You can add up all the World Cups and Super Bowls ever played and they would barely register on the logarithmic total solar eclipse spectacle scale. The one total solar eclipse I saw easily ranks as the greatest thing I’ve ever seen and I’m including the births of my children. The May 20th solar eclipse is annular so it’s not in the same galaxy as a total but annular’s have their charms. At maximum eclipse the Sun appears like a perfect blazing ring of light. In Page it will be 10 degrees above the north-western horizon: a good altitude for composing solar landscape pictures.
By comparison the June 5th transit of Venus will not be a big show. Without proper equipment you won’t be able to see it at all. During transit Venus looks like a little black dot on the Sun. The best way to see this event is with telescope or binocular projection. Under no circumstances should you look directly at the Sun without proper eye protection! For safe transit viewing techniques look here. In 2004 I used binocular projection to view the last transit of Venus from Ottawa Canada. Transits of Venus come in pairs, eight year apart, followed by over a century before the next pair. After 2012 you will have to wait until 2117 to see another transit of Venus. This is our last chance people. Yeah mortality seriously blows.
