2004-2012: the transits of Venus
|
Analysis of the images of Venus in front
of the Sun.
You may have taken images of Venus in front of the Sun.
We also open a database gathering images
of Venus in front of the Sun, in order to use them
in the future for educational purpose. If you wish
to analyse these images in order to determine
a value of the Astronomical Unit, please follow the next procedure:
- the useful images should be dated in Universal Time
(UTC) within one second of time.
- then you may measure the distance between the center
of Venus and the center of the Sun following the instructions provided
in the educational sheet n°07.
-
another method to determinate
the distance between Venus and the edge of the Sun is to send the image
to the center of analysis of the images of the Astronomical
Institute of the Academy of Sciences of
Prague-Ondrejov
observatory.
