Sandra-Leigh Serio: A Potpourri of Astrology Techniques
November 21, 2026 @ 12:00 pm - 6:00 pm
$55 This meeting will be Online via Zoom.
Included in the workshop will be these topics: The Vertex, Dispositor Trees, Sun/Moon Midpoint, Solar Returns, Solar Arcs.
The Vertex is a much overlooked third angle in the chart. It represents fated encounters beyond your control that help to tweak your path and sometimes actually engineer you toward another direction. It is fascinating to look at its impact in compatibility charts, revealing the necessity for two people to come meet.
Dispositor Trees are fun diagrams that often lead to one planet as the supreme ruler of a chart and sometimes two planets (if in mutual reception) or no planets at all. I will teach you how to draw them and interpret them.
Sun/Moon Midpoint is quite interesting in that it shows a strong connection between two people or two events that normally remain hidden. You may ask, “why did I have this relationship with this person, when we have very few planetary connections?” The Sun/Moon Midpoint is the key that reveals the karmic condition.
Solar Returns are indicative of a bird’s eye view of the year ahead. Yet the controversy remains over where they should originate. Should they be from the birthplace, of the location at the time of the solar return or the place of residence? Which one really works or do they all?
Solar Arcs are a much ignored predictive technique. We all love secondary progressions but the Sun is the giver of life so as it moves through the chart its distance from its natal place connects most strongly with the outer planets and easily exposes events not apparent with secondary progressions.
