The ‘Co-Descendant’ (CD) Point

The ‘Co-Descendant’ (CD) Point is an innovation that I created and applied to Solar Returns and Advanced Daily Angles charts early in the 2000’s.  In essence, the CD point works with the Ascendant angle to make the MC angle the focus of a midpoint.

To determine the CD point, we take the arc-distance between the Ascendant and the MC and then project that angular distance from the MC toward the Descendant area of the chart.  This locates the CD point.  Any planet at the CD point, or in hard aspect to the CD point, acts like an ‘intrusion’ factor into one’s life.  This is important to grasp.  

A planet at the CD, along with the Asc. (how we act) places the MC at the midpoint.  The MC then has to adjust to how the Ascendant works with the intrusion of the planet at the CD point.  Several examples will be presented using charts of Ellen Degeneres and Anne Heche.  Ellen is a Hollywood and TV personality, Anne is a Hollywood movie actress.


Ellen’s p.c. Solar Return for 1997 is shown at the left.  We immediately note that her natal angles have realigned with the SR chart’s angles:  This year will represent a major life change for her.  With her n/Pluto-conjunct MC, Ellen is one who inclines to throwing grenades and shocking or manipulating others.

We are interested in the CD point of these charts.  Here, we find the CD point at 6 Gemini.  The math is easy to visually do. Scorpio is three signs (or 90 degrees) from Leo.  The MC is at 28 Leo, the Asc. is at 20 Scorpion, 8 degrees less than the 90 degree square.  So, 82 degrees from the MC, towards the Desc. angle, is 6 Gemini.  The CD point opposes t/Pluto and squares n/Pluto.   A ‘doubled-up’ Pluto can only mean some form of upheaval, irrevocable change, a situation that sets one apart.

Let us look next at a Progressed Daily Angles chart.  This type of chart progresses the Solar Return chart angles by some 1.25 degrees per day.  This value  is an average value as the actual value varies over the course of a year relative to the Equation of Time (EoT).  The EoT notes the apparent greater or lesser value of the Sun’s progress from one noon time to the next noon time.  These changes in value are affected by the orbital motion and distance of the Earth from the Sun and the oblate shape of the Earth as the equator is more or less aligned to or distant from the Earth-Sun orbital plane.


It is reported that Ellen and Anne Heche engaged in a lesbian affair starting on March 23, 1997.  Anne had approached Ellen at a gathering and proposed on the spot that they become lovers.  This was Anne’s first meeting with Ellen.  A very bold introduction, even for Hollywood.  Let us look at this daily chart.

From Jan 26 to this date of March 23rd, we have some 60-or-so days.  The SR MC has advanced from 28 Leo to 10 Scorpio, an arc-distance of 72 degrees.  This fits with the average advance of 1.25 degrees per day on average.

The CD point is at 29 Leo, two degrees from Ellen’s n/MC.  Ellen’s life status and public image will be affected on this date.  The chart’s MC squares Ellen’s n/Venus.  Appropriate.

anne-3-23-1997-jLet us next look at Anne Heche’s Progressed Daily Angles chart for that same date of March 23, 1997.  We find the CD point at 21 Virgo, joining t/Mars and n/Pluto.  This ‘doubles-up’ Mars — note n/Mars-MC-n/MC.  Anne was the one who initiated this affair, so it seems right for her Mars to be strong in this chart.

With Mars and Pluto at the CD point, we see Anne’s CD being the intruder and not the intrusive-upon-her factor.  Other factors in this chart point to this being a highly changing date in her life — note n/Sun-n/Mercury-IC opposite n/Mars-t/Pluto-MC.  What more of an alert do we need to see this as an eventful day?


The chart to the left is Anne’s diurnal chart for April 30, 1997.  This is the date that Ellen unexpectedly announced on her TV show that she and Anne were lovers.

Was Anne surprised?  Note n/Moon at the CD point, square n/Mars and n/Mercury.  “Feelings are strongly influenced by what is said and done.”

So, it would appear that diurnal charts are good vehicles for the use of the CD point.  In fact, it would seem that any cyclic, Return or Advanced chart would fit well with the use of the CD.
