Solar Returns & Daily charts — #1:
The Solar Return chart:
Solar Return charts mark a cycle that starts at birth and continues through our entire life. The MC progresses some 450 degrees per year (360 + 90 degrees) as shown by the 90 degree advance of the MC and three-house rotation of the Sun position in the successive Solar Returns.
I use precession-corrected Solar Returns. While the small amount of slippage in any one year is not great, the accumulated difference between the uncorrected and the corrected Sun position is significant as we get into our adult years, causing the chart to be greatly different in orientation.
The Progressed Daily Angles charts:
The diagram above shows that the “450” degree chart rotation over a year’s time can be un-rolled visually. For any event-date, we can take the interval days from the Solar Return date to te event date and divide it by 365.25 days—giving us a proportional factor. Oct. 2nd is day #275. We can divide this by 365.25 and get a factor of .7529. We can then multiply the arc-distance between successive Solar Returns (4:34 Taurus for 2002, 2:13 Leo for 2003, equals 447:39 degrees which we can convert to 447.65 degrees) by the proportional factor (447.65 X .7529 = 337.03 degrees) we add this to the 2002 MC position and find that the MC moved/progressed 371 degrees.
Since this value is greater than 360 degrees, we subtract that figure and arrive at 11 degrees or Aries 11 degrees. Our software offers an MC progressed to Aries 7 degrees, utilizing a more sophisticated formula (Equation of Time variations, for example). Plus, I’ve done some rounding off of the figures used. But, this provides the basis for understanding how these in-between daily charts are determined.
More detail and discussion:
In other posts I will discuss the other factors that go into the use of precession corrected charts, the significance of the MC-Solar Cycle and its sensitive points, why it is important to recognize when natal chart angles return to solar return or daily chart angles, the focus on planets that are contacted by these rapidly progressing angles, etc. Again, if there are any comments or questions that need to be advanced, just post a comment here or contact me directly at my e-mail address: dadsnook@charter.net Dave
