One of the aimes of this project Venus Transit was the exact assessment of four important moments in course the transit:
- the moment when Venus' disc first "touches" the solar
limb (the first contact)
- the moment when Venus' disc has passed the solar limb and is inside solar
disk (the second contact)
- the moment when Venus' disc first "touches" the other side of the solar limb
(the third contact)
- the moment when Venus' disc passes the solar limb(the fourth contact)
Because of the bad wheather we couldn't time the first pair of contacts and the
remaining contacts we could time only approximately.
For example this cloud overlap the Sun only few minutes before the third
contact.
