Latest Comment (June 8, 10:38 UT) : Weather seems to cooperate today and many people can enjoy the sight. Three videos from the AGAPE group at ESO are now available - the entry of Venus onto the solar disc, the first part of the passage across the disc and the second part of the passage across the disc. If you missed the beginning of the Venus transit, you may access all previous versions of this Central Display page in the Archive.
A transit - either of Mercury or Venus - always begins on the eastern limb of the Sun and ends on the western limb. This is in direct contrast to eclipses - either solar or lunar - which always proceed from west to east. The reason for this is that Mercury, Venus and Earth move around the Sun in the same direction - from west to east, as seen from the Sun.
There is now just one hour left until the 3rd contact when Venus will again touch the border of the Sun.
