2004-2012: the transits of Venus 

The VT-2004 databases 

 

We propose four databases gathering the observations made in the whole world on June 8, 2004 through the VT-2004 network.

  • the timings of the observations of contacts (first access): this database provides all the observations made on June 8, 2004 through the VT-2004 network and used the on-line calculation of the AU. These data rae accessible using longitudes and latitudes of the observing sites.
    For access to the database, please click here (in case of cookie problem, please reload the page).
  • the timings of the observations de contacts (second access): this database provides selected observations (we eliminated poor observations). The data are more easily accessible thanks to geographic zones.
    For access to the database, please, click here.
  • the images of the contacts Venus-Sun: These images made before and after the contacts allow to determine the timings of the contacts by interpolation of the dates of the images.
    For access to the database, please, click here.
  • the images of Venus in front of the Sun: These images have been made on June 8, 2004 during the transit. We selected images allowing to determine the distance between the center of Venus and the center of the Sun.
    For access to the database, please, click here.
All these data allow to calculate a value of the Astronomical Unit thanks to the formulae that we propose in our educational sheets n°04 et 05.
