COMMENTS ON THE RESULTS: We gathered almost 12 hours of video recordings in the two video recorders annexed to the telescopes and Antonio Vides and his camera recorded all  the activities. Diego took 38 raw of pictures with the  LPI, saving 502 files, almost half a gigabite. Observing  the images and locating the points of contact was easy but  to process them was a bit harder. (We are still working on it. Processing Webcam Images with RegiStax)

Team  ESTUARIA3 was not able to determine any of the instants of contact because they could not dominate the projection supporting bar. And team ESTUARIA6  was not able to determine any instant of contact with the filter glasses because of the small size of Venus with the naked eye.
