2. This sight...is by far the noblest astronomy affords... -Edmund Halley June 2004, Rashidabad “This sight...is by far the noblest astronomy affords...” Edmund Halley • KaAS observed • Next session?

3. Outer planets can never be at inferior conjunction

5. In 1996, descending Venus just barely missed transiting the sun.  For 2004 and 2012, Venus crosses in front of the sun's disk.  In 2020, the planet is sufficiently far above the plane of the earth's orbit when it descends to the right of the sun and thus does not transit the sun. Similarly, not until this line of inferior conjunction regresses to the opposite node, after many eight year cycles, will the next pair of transits occur at Venus' ascending node in December, 2117 and 2125.

6.  THERE WERE FIVE CONJUCTIONS IN EIGHT YEARS 5 x 583,917 days = days 2,919.585    8 x 365,256 days = days 2,922.048

7. Venus is on its ascending node on 9 December, the descending node on 7 June. Almost exactly 243 years held 152 rounds and 395 synodic Venus cycles Frequency is 105.5, 8, and 121.5 years
