The countdown to the Transit of Venus across the Sun has begun. Will be the second and last of this century. The first, visible from Europe, took place on June 8, 2004.
On 5 June (June 6 in Asia and Australia) Venus will pass between Earth and the Sun producing what is known as Transit. The Venus Transit is the transit of Venus as seen from Earth. It occurs when the Sun, Venus and Earth are aligned. Transits of Venus are very rare, occurring 4 transits in 243 years. The next transit will occur on December 2117, so I do not want to miss this transit because surely we can not stay more than 105 years, right?. If you want to observe the Transit do not wait until the week or a day before to start with the preparations, because you could miss one or another detail.
A transit can only occur with inner planets like Mercury and Venus as they are the only ones that can be between the Earth and the Sun during their orbits. This combination is called Inferior Conjunction and refers to when in this case, Venus passes between the Earth and the Sun

Before we begin, we present a traffic visibility map, so you can know if it will be noticeable from where you are or if you have to settle for seeing only through photographs or via streaming.
Astronomers said the celestial event can be seen almost anywhere in the world, but only residents in Hawaii and Alaska will have the opportunity to see all the 'walk' the planet from the Sun, which will last about seven hours and will start this 5 June at 3:09 pm (Pacific Daylight Time-22: 09 UTC). This favors observers located in the middle of the Pacific, because the Sun will be near the zenith when Venus crossing in front of it. Creative photographers will rejoice at the prospect of photographing a swollen red sun "bored" by the circular disk of Venus.

TIPS FOR THE OBSERVATION OF THE TRANSIT OF VENUS
- First, do not stare into the Sun, Venus hides a portion of the solar disk is too small to cover the blinding light. Not observe the Sun using an optical instrument (binoculars or telescopes) that lack of proper sunscreen.
- Second, use a welder's filter No. 14 (easy to find in places selling welding) or polycarbonate film filters, as the Baader AstroSolar.
- Third, if you have a telescope, but there is no filter, the Sun's image projected on a screen near the instrument.
- Finally, keep in mind that the film negatives and X-rays do not provide adequate protection for observation.
- Many astronomy clubs fitted solar telescopes to observe the event. Contact your nearest local club for details.
Because the orbits of Venus and Earth are not in the same plane. So we can see the traffic has to match the alignment Earth-Venus-Sun is produced at the nodes, ie the intersection of our orbits. Typically, when this situation occurs, Venus is very above the sun, veryry below.
The passage of this year is the second of a pair separated by an interval of 8 years. Expectations were high in June 2004 as Venus approached the sun. No one who was alive at the time they saw a transit of Venus with their own eyes, and hand-drawn sketches and grainy photographs of past centuries not be compared with what was going to happen. Modern solar telescope captured an unprecedented view of the Venusian atmosphere, lit from behind by the fire. They observed from the Sun to Venus transit the Sun's crown and eerie silence across such large magnetic filaments that could engulf our planet. A photographer even captured the image of a spacecraft, the International Space Station (ISS, for its acronym in Spanish), while conducting its transit of the sun along with Venus.
This year's event promises to be even better, as cameras and solar telescopes have incorporated more technology. In addition, the Solar Dynamics Observatory (SDO Solar Dynamics Observatory, or, for its acronym in English), NASA, also observe the transit. SDO produce images of this unusual event will have the same quality as that takes the Hubble Space Telescope.Remember there will be another. Not for us. The transit of Venus is a rare phenomenon that occurs twice in an interval of 8 years and then not again be another to more than 100 years later. As mentioned above, we had one on June 8, 2004, we now have it from 5-6 June 2012 and the next will be on December 11, 2117. I don't think any of us will be here in 105 years.
The Transit of Venus in Colombia will begin at 5:05 pm The best place to watch it in Colombia is the Archipelago of San Andres, Providencia and Santa Catalina, where the sun sets at 6:50 pm. But the deadline to see it varies in the rest of the country, in Bogota will be at 6:06 pm, Manizales and Pasto, 6:13 pm, Medellin, 6:15 pm, Cali, 6:14 pm, and Santa Marta, 6:18 pm I would not miss this unique opportunity to closely observe a planet similar to Earth as it passes in front of a star like the Sun Do you?.
