Hello group;
I updated my web site with August 17 extrasolar transit of newly
discovered planet TrEs-4. This is my best result so far and the shape of
the transit is quite definite. This planet is 1.7 times larger than
Jupiter and has an average density only of 0.2 g/cm^3. The depth of the
transit was of 0.01 manitudes and the precision reached is +- 0.0014
magnitudes (at the beginning, and 0.002 magnitudes at the end, because the
lower altitude). Here is the direct link to the transit:http://www.danielegasparri.com/eng/t...lar/tres-4.htm.
Clear skies!

A solar system transit is the most immediate experience of Copernican
reasoning as it represents the point where a planet ,in an inner
orbital circuit , overtakes the slower moving Earth with the central
Sun in the background -

Copernicus and Kepler did not have telescopes to admire these
brilliant heliocentric events and they relied on the faster Earth
overtaking the slower moving outer planets to infer the Earth's
orbital motion between Venus and Mars around the central star -

The next event in 2012 should be promoted as a once in a lifetime
chance to appreciate Copernican reasoning directly,instead it will
diluted to an astrological theme of Venus 'crosses the face of the
Sun" and nothing else.
