Rate for User Defined Directions

In addition to the solar arc, ascendant arc and vertex arc rates of direction, it is possible for the user to specify their own annual direction rate, for use in casting directed charts or in dynamic reports. The existing arc rates that are pre-defined are as follows.

•Solar Arc - the arc of the secondary progressed Sun. This has an average rate of motion of about 1 degree per year.

•Ascendant Arc - the arc of the ascendant, as derived from the Midheaven when it is progressed by the secondary progressed solar arc. This has an average rate of motion of about 1 degree per year, but varies somewhat.

•Vertex Arc - the arc of the vertex, as derived from the Midheaven when it is progressed by the secondary progressed solar arc. This has an average rate of motion of about 1 degree per year, but varies somewhat.

In the "Preferences" dialog, "Progs/Dirns" tab you can define your own fixed rate in terms of annual longitudinal motion in degrees. You can select a previously entered rate from the drop-down list or simply enter an annual arc rate in degrees and minutes, or in decimal degrees. See Entering Angles for a more detailed descriptive of acceptable formats for entering angles. The last ten angles that you enter here are stored in the list for easy reselection later.

The direction rate selected here will be used whenever you select to use the User Arc Directed chart method when creating a directed chart from the Progressed option of the Charts menu. This rate is also used in dynamic reports whenever you select User Arc from the Direction Type option of the “Dynamic Report Selection” screen.
