• Parameters at the instant of the conjunction in longitude.
• General phases.
• Geocentric phases.
• Back to the canon of the transits of Venus.

All the instants are given in Universal Time, for the present date the value of the difference between the Terrestrial Time TT and the Universal Time UT is taken as 6438.60s
Longitudes are counted positively towards West and negatively towards East.
