Short tutorial of the celestial fundamentals
It is summer in North Hemisphere and it is 11 am. Sun's declination is 23.5N
The semi diurnal arc (rise to culmination ) of Sun is 128 or 8h32m
But the Sun has only risen 77 of this - or 3/5ths of the arc.

J upiter's declination is 15S, so its semi-
diurnal arc is 112.
But J upiter has only risen
45 - or 2/5ths of its arc.

So - for J upiter to be
Directed to the Sun
the celestial sphere
needs to rotate a further
1h28m so that J upiter
travels 1/5

J upiter is now

both 3/5ths of their
diurnal arcs
SoJupiter was Primary Directed
to Sun 1h28m after birth, or at FY, at age 22.

Because of their differences
in declination, J upiter needs
67and Sun needs 77 to trace
their 3/5ths portion of their
diurnal arcs for them to be
'conjunction' in Primary
Direction.
