The MC-Solar Cycle; part One.  Sun in houses during the annual cycle.

When one looks at the birth chart and then the first Solar Return at age one, or any two subsequent Solar Returns during a lifetime, it is apparent that the MC of the latter chart is located some 90 degrees further along the zodiac circle than the previous chart.  Of course, this means that the Sun has also shifted house position in the latter chart some three houses clockwise.

The diagram at the right may make the above statements clearer to picture. Let us note that the first-prior Solar Return has the Sun in the 3rd house.  The MC will exhibit over the course of a year a Rate of Advance of some 450 degrees instead of the apparent 90 degrees.  360 degrees plus 90 degrees equals 450 degrees.  Keep this in mind.

After 4 months and 3 weeks, the diagram shows that the Sun’s position has moved to the 9th house, exactly opposite the Solar Return (S/R) Sun position.  At 9 months 2 weeks, the Sun has returned to the prior S/R house position (although we know that the Sun has only moved some 9 1/2 signs in those 9 1/2 months.  At the end of the annual Solar Return year, the Sun is positioned three houses further, clockwise, in the chart, while the the MC has advanced five 90 degree segments — or 450 degrees.

(Edited to add, 8-13-10)  In actuality the MC rate of advance is a combination of the daily advance over the year of 360 degrees plus the actual advance of the MC for the additional one-quarter of a day that is required for the Earth to return to its natal position along our orbital path.  This quarter-day is, of course, added each year to make up a full day that is applied to our leap-year every four years.  This cycle is then a hybrid of a “day for a year” plus an actual quarter day, the 360 degrees and the 90 degrees adding up to 450 degrees as shown in successive solar return charts.  This value is proportioned to approximately 1.25 degrees per day and adjusted by applying the Equation of Time variation for the days involved when “progressing” a Solar Return forward to a particular “in-between” day for an event.  Like other progression rates used by astrologers, this rate works quite well for our purposes.

You can test these rates of motion by calculating a series of charts for several successive days for the same clock-time.  The Sun will be seen to have moved, on average, a bit less then one degree.  Afterall, the Sun has 365.25 days each year to move only 360 degrees; hence the daily movement is a bit less than one degree.  On the other hand, the MC moves faster, about 1.25 degrees per day on average since it will move 450 degrees in 365.25 days.  This Rate of Advance is not a flat linear rate but a combination of a flat rate plus a modification related to the Equation of Time (a variable rate).  Astrologers familiar with manual chart calculations will understand the Equation of Time quite readily.

This MC-Solar Cycle is akin to the human gestation cycle, and it starts at birth (and perhaps at conception) and continues as a regular, continuous cycle throughout our life and beyond.  We see examples of this in the charts posted on this site.  Dave.

The MC Solar Cycle; Part Two.  Trio of natal, solar and daily charts in Solar-MC cycle.

The fact that we can define, measure and rely upon this cycle which is a “rate of advance” (flat rate progression modified by the variation of the Equation of Time) of the Solar Return MC and the transiting Sun, permits us to view and use the natal chart, solar return, and the (in-between) daily charts as a trio of unified charts!  Each chart in this trio has its specific role in relation to the other charts — something that has never been recognized by other astrologers in this manner.

  • The natal chart can be viewed as expressing our potential.  “Potential” has been overly used, but we can use it here in a meaningful way, as will be seen.  The natal chart can also be used to assess personality and character patterns and be used for other areas of exploration, but we will stick with “potential” here.
  • The solar return will represent the theme or focus of the current year when “potential” is expected to be presented in terms of action, attitude and situations. These will be portrayed by both natal and solar return (or transiting) planets found near the angles of the solar return chart.
  • The progressed daily angles chart is so named to differentiate it from the Sidereal PSSR (Progressed Sidereal Solar Return) chart which utilizes the planets of the solar return in their progressed position of the year.  The PDA chart instead uses transiting planets along with natal planets and angles as the basis for determining which actions, attitudes and situations are likely to be experienced on a given date.

In using these three chart types we have to remember that we are dealing with a unified set of charts which together provide a context of potential, theme and daily experience! Context is an important word to consider here.  The natal “potential” cannot be experienced and developed all at once, but is most likely to encountered and developed bit-by-bit over time thru our opportunities and challenges, our interactions with others, and shaped by our own actions, attitudes and situations.

Accordingly the individual and associated patterns of natal planets have to have their meanings carried forward into the solar return chart and into the daily chart — as indicated by which of them have their transiting counterparts at the angles of those charts or are positioned themselves (natal version) at those chart’s angles.  In the next section we will return to the above diagram and discuss the relationships between the natal, solar return and angular daily chart patterns and how they are applied to the predictive process.  This will be exciting.

Future sections of this essay will explore these several points in more detail.  Until then, questions or comments can be posted here or you mail e-mail me at for your private responses.  Dave

The MC-Solar Cycle; part Three — Natal angles in contact with solar return chart angles.

When angles re-align with angles!  This was my most thrilling “discovery” when I first started working with these charts so many decades ago.  There are several versions of “angles to angles” that occur as the MC in the Solar Return chart advances on a daily basis at the rate of 1.25 degrees per day (approximately).  First, we have the S/R angles advancing to the point where they are reversed (at 4 months, 3 weeks) and when the S/R angles re-align with their initial position (at 9 months, 2 weeks).  Second, we have the situation when natal angles are aligned in some manner with the solar return’s angles on one’s birthday.  Third, when the advancing angles move from their S/R positions and make contact with natal angles.  This portion of this essay will address this second situation.

The natal MC is aligned with the solar return MC: If you reside at or near your birth location, the Ascendant and other angles will also be aligned.  Think about what this means!  If it was important for you to be born with this angular alignment, then it must be equally important at this point in your life to re-define just what those angular power positions can represent for you.  This is the time to focus on your natal potential, either to make an effort to experience it, or to experience a change in overall plans and direction for your life.  In any case, this is not likely to be a quiet period for you.  Life will change for better, for worse or just to take a different path.

The natal Ascendant is aligned with the solar return MC: You are likely to have to speak or act in some significant way relative to your goals in life, your reputation or your leadership-representation of other’s affairs. This should be quite easy for you to make and understand this linkage as it builds upon common astrological symbolism.

The natal IC is aligned with the solar return MC: We are dealing with a chart angle reversal, specifically a reversal of the vertical axis as the latitude distortion of Ascendant placement may not cause a re-alignment of the Ascendant with the Descendant.  This reversal naturally bring into play the interconnection between one’s outer life (work, reputation, stated goals) and one’s inner life (family, home, core values and resources).

The natal Descendant is aligned with the solar return MC: This coincides, of course, with the natal Ascendant aligning with the solar return IC angle.  Relationships, partnerships and the effects of social interaction will have to be addressed and most likely changed for any of several reasons.

How do these angle-contacts really express themselves? This will relate to which, if any, planets (natal or transiting/solar) are at or close to the angles of the solar return chart.  One needs to understand how the natal planet and any planets it tightly aspected were expressed in one’s life, and then you can extend this typical expression to that planet’s role at one of the current solar return chart angles.  For example, if natal Mars in Cancer at the natal IC angle is now (in its transiting version) at the MC in Libra, we might find that a defensive attitude about one’s family life/situation has to now be diplomatically addressed in terms of how it impacts your public goals and reputation. That is just one of many possible applications, but it gives you a sense of how planets and angles are dealt with.

Since these short essays cannot be a substitute for a book or a class setting, you are encouraged to 1) explore these and other combinations on your own, 2) follow and consider the examples that have been given in this blog site, or 3) submit a question through the comments section or e-mail me directly at    Dave

The MC-Solar Cycle, Part Four — Static Charts and Cyclic Charts.

The natal chart represents a snap-shot picture of the stars and planets about the Earth at the moment and location of our birth.  While the sky includes many changing phenomena, we use the chart as a static reference tool.  We may note transits across that chart but the chart itself remains useful as a static portrait.

Referring to the wave and buoy diagram, (right side) the buoys can represent static or sign-degree positions which may represent natal chart angles or natal chart planet positions.  The wave may represent transiting planets.  The natal chart positions are static, only the transits change and its is this “change” which activates a particular sign-degree position.  The zodiac is not the “energy”, the planets are the energy in a static chart.

In actuality, a transit chart represents changed planet positions which are typically related to the static chart and chart angles of the natal chart.  The transit chart could be said to be a hybrid chart consisting of a fixed framework and a changed set of planet positions.

On the other hand, Solar Returns and daily charts linked to the MC-Solar Cycle have chart angles and planets that are in motion—or we might say that each chart captures the motion pertaining to that chart’s date and location.  The angles of each chart change relative to charts cast for earlier or later days and the planet positions also change.  Unlike the natal chart which stands as a reference chart that does not change, these cyclic charts are used for their associated dates only—they are not ongoing reference charts used over a lifetime.

So, the question is, “How do we use these charts in a manner which is different from how we use a natal chart?”  The MC-Solar Cycle, incorporating both the Solar Return and the 365 Progressed Daily Angles charts, can be related to the wave and buoy diagram shown above in a manner that is different from how we saw the natal chart relating to that diagram.   1) The buoys can represent current planet positions and fixed natal planet positions, 2) The wave can represent the constantly advancing angles of the MC-Solar Cycle chart framework.

This view requires that we see almost everything as being in motion!  Only the natal planet positions will be constant in this shifting seascape.   This sophistication of how we view and work with moving charts seems to place more demands upon the astrologer.  Yet, astrology is essentially an understanding of cyclic interactions as they relate to the natal chart’s imprint.  Modern day astrology seems largely focused on this ‘imprint’ of the natal chart.  Yet, that focus actually limits astrologers in applying interpretive methods to an increasingly complex living model that each of us possesses.  There are only so many symbols in the chart, and so few options exist  for applying them to houses, aspects, signs and other associations.

Part Five:  Example charts, using Donald Trump’s 2016 Solar Return.

Donald Trump was born on June 14, 1946 at 10:54 AM, Jamaica, New York 073w48, 40n41.  His 2016 p.c. Solar Return is shown below.


In this p.c. Solar Return for 2016, Donald Trump’s Sun-Sun is in the 11th house indicating some level of outreach to a surrounding community.  In his case the ‘community’ was the whole U.S. nation as he was running for his party’s nomination for U.S. President.  Trump has one planet angular — n/Pluto.  He has a sense of being powerful, a feeling engendered by his seeminly ease sweep over some 16 rival candidates.

I had discovered years ago the usefulness of making the MC a midpoint between the Ascendant and another point near the Descendant.  This is done by taking the arc-distance from the Asc.-to-MC and applying from the MC westward.  This creates a point at 22 Aquarius, a point I call the Co-Descendant.  Any planet at, opposite, or square this point acts as an intrusion into one’s life, forcing the MC to accommodate  the interaction between the Ascendant and the planet at the CD point.  There is no planet in this chart near the CD, but there is a planet, n/Mars, opposite the CD.  Mars and Pluto don’t pair up as a couple of nice guys.  Trump’s behavior during this S/R period was anything but nice, carrying on his nasty behavior exhibited during the long series of candidate debates.

On Nov. 9, 2016, Trump’s 2016 Solar Return chart’s MC angle had progressed 180 degrees to reach the point opposite the daily chart’s MC.  This progressed MC was at 0:40 Taurus, a fast moving portion of the zodiac — the next day it would be at 2 Taurus.


The pda MC reaching an oppositional point to the Solar Return MC constitutes a challenge or a crises or a change of some sort.  It comes around 4 months and 3 weeks following the S/R date.  In these 140 days, or so, the MC angle progresses 179 degrees (at a rate of 1.21 degrees per day).  The Equation of Time variable (minus 16 minutes) retards the average rate of advance of 1.25 degrees per day. Other important dates occur when the progressing S/R MC moves to the daily chart’s Asc. or Descendant, or the Solar Return’s Co-Descendant or CD point.  Nov. 9th was the day after the U.S. national election.  Many had gone to bed expecting Hillary Clinton to be the winner.  Upon waking, it was learned that Donald Trump had won the election.

Equally important is the date when the S/R’s progressing MC of 1:56 Taurus reaches the S/R CD point of 22 Aquarius.  At this stage one’s plans are often altered by external events or other people having influence in our life.  The chart below shows this — and it provides some surprises for us to consider.


This date is in the future from the date that this is written (Dec. 26, 2016).  We will have to wait to see what transpires.


  • First, the daily chart’s MC has reached the S/R chart’s CD point.  n/Uranus is at the Asc. angle.  n/Uranus-n/Node/n/Sun seems to be Trump’s trigger point as it opposes the n/Moon.
  • n/Moon and t/Saturn will soon be contacted by the advancing angles, as well as n/Mars-n/Asc. In a case like this we might expect a two-part event.  Something or someone will rile Trump up big time and then, a few days later, an intentional use of force or an attack of some kind will be seen.
  • For this chart the MC has progressed 290 degrees in 233 days, average rate of advance is 1.24 degrees per day.

Several weeks later, at the end of March, the progressing MC will return to its S/R position.  Note the following chart.


As can be seen, the advancing angles of the chart have brought the MC back to the 2016 Solar Return’s MC angle.  On this date we note a couple of factors.

  • t/Moon is on the MC.  The public will note any emotional outbursts on this date.
  • n/Pluto-Asc.  Trump will likely force some issue.  t/Mars is broadly square n/Pluto.
  • The MC of this chart has advanced full circle in 288 days for 2.24 degrees per day.

Part Six:  Riyal’s “Hit List.”


When you create a Solar Return within the Riyal program, you are led to a screen that asks if you wish to see any of a small selection of charts.  In this case, choose PSSR (which is the Sidereal term given by Cyril Fagan to S/R progressed charts.  For precession-corrected Tropical Solar Returns I call these Progressed Daily Angles charts.  Once that choice is made an annual listing of dates appears, as shown above.  Right clicking on any date/line will pop up a chart for your use of the progressed daily angles for that date.

This permits the astrologer to browse through an annual period and quickly find dates when certain characteristics will be present.  In this case the March 29th, 2017 date showed the MC at 1:08 Taurus.  The MC portion of the MC-Solar cycle was complete.  This was some two and a half months before the Solar cycle was complete.
