One can progress a solar return chart just like a nativity, with Secondary progressions. One should use Standard Quotidian to progress the angles, or use the Sun/MC phase angle from the solar return to advance the Midheaven by the transiting Sun. The Moon will move about 13 degrees or so, and the MC...

Secondary progressions are based on the 1 solar day = 1 solar year principle. However, for Tertiary progressions 1 solar day = 1 lunar month. Mark It is becoming increasingly apparent that the Sidereal day, and not the Solar day, should be used in calculating these progressions. The position of the...

C. C. Zain and the Church of Light do not use Tertiary (1 day = 1 lunar month) progressions. They use Minor progressions (1 lunar month = 1 year). They also calculate Minor progressions based on the phase angle between the natal Sun and Moon applied to the transiting Sun to calculate the Minor progr...
