Predictive Astrology

Predictive Astrology

Predictive Astrology refers to the branch of astrology focused on forecasting future events, mapping psychological phases, and identifying optimal timing for human activity. Utilizing time-lord techniques, transits, progressions, directions, solar returns, and eclipses, this practice evaluates how unfolding planetary cycles interact with natal placements to reveal potential developments, environmental trends, and dynamic windows of opportunity or challenge across a person’s lifetime.

Solar Returns (lecture notes) – revised, with additional notes

Solar Returns, Predictive Astrology, and Applied Astrology. This archival manuscript is a set of revised lecture and instructional notes on Solar Return charts by Marion D. March. March outlines the technical principles and interpretation rules for Solar Returns, which freeze transits for the exact annual moment the Sun returns to its natal position. She advocates calculating the return chart for the individual’s current place of residence rather than their birthplace. The guide details interpretive priorities, including the Solar Return Ascendant, rising planets, the house placement and aspects of the Sun, the natal house coming to the Solar Return Ascendant, and hemispheric or angular distributions. Additionally, March provides specific astrological signatures for predicting major life events, such as marriage, childbirth, career changes, relocations, divorces, and health issues.

Solar Arc Directions

  • -2

Solar Arc Directions, Predictive Astrology, and Applied Astrology. This archival document is an instructional reference guide titled “SOLAR ARC DIRECTIONS” by Marion D. March. March outlines the mathematical calculations and practical applications of Solar Arc Directions, secondary progressions, and planetary transits. She distinguishes progressions as internal attitudinal shifts, directions as visible outer developments, and transits as concrete environmental triggers, recommending a combined approach in practice. The text includes step-by-step mathematical instructions for calculating True Solar Arc increments, illustrated by a case study of author Kitty Kelley across key career and life milestones. Additionally, March details planetary orbital speeds and presents a four-quadrant cyclic model structured around the chart angles to track long-term personal and vocational development.

Progressions, Solar Arcs, and Transits (One-Page Summary)

Predictive Astrology, Timing Techniques, and Astrological Practice. This archival document is a one-page instructional guide titled “PROGRESSIONS, SOLAR ARCS, AND TRANSITS” by Marion D. March. March synthesizes the core operational differences between secondary progressions, solar arc directions, and transits. She defines transits as external environmental forces, secondary progressions as shifts in internal consciousness and attitude, and solar arcs as hybrid tools reflecting both psychological shifts and timing events. The sheet covers practical calculation guidelines, including a strict $1^\circ$ orb for progressions, checking critical $0^\circ$ and $29^\circ$ degrees, evaluating sign and house shifts, and prioritizing aspects formed between progressed planets and the natal chart over progressed-to-progressed aspects. Additionally, March details the activation of natal configurations (such as a natal T-Square resolving into a progressed Grand Cross) and explains the duration and impact of transits.

PLANETEN UM DEN SOLARAZENDENTEN & SOLARE

Solar Returns, Predictive Astrology, Timing Techniques. This German-language instructional manuscript titled “SOLARE” by Marion D. March provides a guide to interpreting Solar Return charts. March explains the core mechanics of Solar Returns, which cast an annual snapshot when the transiting Sun returns to its precise natal position, emphasizing the importance of calculating the return for the individual’s current place of residence. The text outlines interpretive criteria including zodiac signs on the Solar Ascendant, the placement of the Solar Ascendant ruler across natal and solar houses, planets positioned near the Solar Ascendant, house placements of the Sun and Moon, and hemispheric distribution of planets. Additionally, March provides criteria for predicting specific life events such as career changes, relocations, marriages, divorces, pregnancies, and financial shifts, illustrated alongside technical Solar Return worksheets and case studies for figures including Luciano Pavarotti, Ernest Hemingway, Pablo Picasso, Boris Becker, and Hermann Hesse.

Mundane Lessons

Mundane Astrology, Political Astrology, and Predictive Astrology. This archival document is an introductory reference guide titled “MUNDANE ASTROLOGY” by Marion D. March. March details the principles and interpretive rules of political and mundane astrology, which applies astrological symbolism to nations, cities, and mass populations rather than individuals. She outlines key predictive timing frameworks, including Solar and Lunar eclipses, Lunations, and Solar Ingresses—highlighting the Capricorn Ingress as particularly critical for world governments and international relations. The text provides extensive, specialized mundane definitions for all twelve astrological houses, the ten primary planetary bodies, and the twelve zodiac signs. March categorizes their specific applications across political structures, economic indicators, societal movements, agricultural conditions, international diplomacy, labor relations, intelligence agencies, and meteorological phenomena.
