  Westran thinks a plausible answer to this question continues to emerge from a systematic research effort aimed at merging synastry aspects with another well established technique astrologers call secondary progressions.  When astrological students are first introduced to the subject they learn that astrology deals with angles the Sun, Moon and planets form between each other as they hurtle through space at orbital speeds dictated by the varying distances between them. "Different angles symbolize different relationships, correspondences or outcomes," he said.  Astrologers use secondary progressions to help time events in people's personal lives. Simply, with this technique, they calculate how far the Sun, Moon and planets have progressed around the horoscope wheel using a day for a year formula. For every year that passes, the Sun, Moon and planets are advanced the same number of degrees on the horoscope wheel that they have actually traveled through space in a single year, either forward or backwards (if retrograde).  The Moon orbits the Earth - and the planets orbit the Sun - at widely varying but predictable speeds. The Moon makes a great deal of progress around the horoscope wheel in a single year; distant Pluto not so much, he explains.  In the information age, high-speed computer programs make it relatively easy to create progressed birth charts. For example, for someone who just turned 00, the astrologer simply counts forward 00 days from the individual's date of birth and casts a progressed birth chart for this date. It's the astrologer's task to compare and analyze how the progressed planets interact with natal planets in the individual's birth chart.
