Orbital Progressions, the new timing technique defined and illustrated within this book, provide noteworthy data and insight. They are a "mean" calculation, tracking the constant rate of planetary revolution around the Sun, as opposed to Secondary Progressions which track the "true" movement. Whether you are an intermediate astrology hobbyist, or an experienced professional astrologer, Orbital Progressions are sure to pique your curiosity. If you are interested in predictive astrology, or understanding the current expression of your natal chart in greater depth, this book is for you. The celestial alignments within the charts presented exhibit why Orbital Progressions should be an addition to any delineation toolbox.
