Calculating the Out of Bounds Moon
With so many different kinds of astrological software in use, the simplest suggestion is to just go to the “Help” files in the program you use and look up “Declination.” There you will see how to display it for any chart you calculate. Declination will be given as either North or South, sometimes shown as a + or - . If the value exceeds 23°28', it is Out of Bounds. This will work for both a natal chart or a progressed one.
Using Solar Fire
Out of Bounds Moon
Calculate or open a chart. Click on “Reports” in the top line. Click on “Current Chart.” A window opens titled “Chart Reports & Tabulations.” Under “Chart Points,” you will see a column labeled “Decl.” That is declination. Check to see if the Moon’s value is 23°28' or greater. If so, it is Out of Bounds. Again, this will work for both a natal or progressed charts.
Progressed Moon Declination Cycle
To watch for the Moon progressing Out of Bounds over longer time-scales, open the natal chart, then click on “Dynamic” on the top line. Click on “Graphic Ephemeris.” Open “Saved Selections,” scroll down and click on “Declination of Moon (one year).” Under “Period of Report,” click the “Years” button (unless you want to zoom in on a specific period of your life).
