Using a 45 degree graphic ephemeris

by Mary B. Downing

 The graphic ephemeris shows planetary transits as curved lines progressing from left to right and top to bottom.  In the 45 degree format, 0’ of the cardinals is at the top and continues downward for all 30 degrees.

 It is immediately followed by the first  15 of the fixed signs, which then wrap around to the top and continue downward another 15.  At that point we start the mutable signs, which continue to   the bottom of the graph.

 The planetary positions begin at the left, and continue across to the right.  While they are going downward, they are in direct motion, when they are going upward, they are in retrograde motion.  Across the bottom of the graph is a time-line.  The longer lines are Sundays.

 All connections on this graph are 8th harmonic multiples: 0,45,90,180 etc.  The attached chart was calculated by TG2, a DOS Astrolabe product.   It will calculate charts in any harmonic, secondary and tertiary directions and declinations.  Of course the computer program also reads already calculated data and draws in the natal chart.


Setting up your chart:

Enter your planetary positions and angles on the left-hand side of the chart, and using a ruler or T-square, draw them horizontally across the graph.  Mark transit contacts with a hi-liter.  Depending on your interpretation of individual planets, you may want to additionally mark Mars, Saturn, etc. with red and Jupiter, Venus etc. with green for quick reference.

You’ll notice on this graph that the transit moon has been omitted (for visual clarity), but that new moons, eclipses, sign-changes and stations are indicated.


How to read a graphic ephemeris:

You may find a transparent ruler a handy tool to determine the date of a planetary configuration.  The beauty of a graphic is all transits show in a dynamic format.   We see mutual aspects forming and separating, approaching and returning.  The rhythm and flow of planetary pattern is visually displayed.  It is extremely easy to immediately see active periods, see if they repeat themselves, see more serene time frames.  It allows for overall planning at a glance, and equally shows when more detailed analysis is necessary.

Since the Graphic Ephemerides can be calculated in any harmonic, they can be used to investigate 5th, 7th, and 9th harmonics as well as 45 or 30 combinations.
