The Point of Sonia-- A Point of Personal Transformation

In January of 1998, I gave a lecture for the Washington DC NCGR group based upon research that I had conducted in 1990 with some of my best astrology students. Our goal was to take birth and death charts and assess if there is some easy-to-spot, reliable pattern for determining the possibility of death for an individual. As a responsible astrologer, I never speak of death with any client. This project was conducted for pure research. This information should not be used to warn a client.

In my 30 years of study in astrology, I can easily determine a death “around” an individual but it has been difficult for me to spot those factors that contributed to the death of an individual. While I was originally writing this article, a client and her husband were both experiencing the transit of Pluto square to the natal Saturn. The husband died suddenly but my client lived. Could it have been determined ahead of time who was in danger? The husband did not have an accurate birth time so I cannot use this example.

In our project, only examples with accurate birth and death times were used. There were different types of deaths – by accident, by heart attack and by cancer and even a death at birth. I also have a large collection of charts with accurate birth times but not the time of death or, in several cases, the date of death is only approximate.

In this project, I used secondary progressions, solar arc progressions, transits to the natal and progressed planets, the eclipse before death and, if this eclipse was a lunar eclipse, I also included the solar eclipse before death.

Initially, I included the Part of Death but, when this proved irrelevant, I discontinued using it. We experimented with several planetary “part” combinations. One of my particularly intuitive students, Sonia Valdizan, suggested the following combination: Jupiter + Ruler of 4th Cusp – Descendant or the 7th House Cusp. We noticed the significance of these points at the time of death. This combination worked in every case. We now call this point in the chart “The Part of Sonia,” named after its discoverer. Since Sonia was born in Cuba, we refer to it as a Cuban Part rather than an Arabic Part.

The two chart examples that I used in the original article were selected solely because I have the permission of the families to publish the charts. I do not have the space in this article to reprint the chart maps. In the chart for “Harry,” the significant trigger aspects were: Solar Arc Saturn at 20°59’ Aries aspecting both the natal Moon and Mercury (near the 4th House cusp); Solar Arc Venus 15° Jupiter/square Nodes and opposing transiting Pluto; transiting Sun-Mercury-Venus in the 8th House near the natal Neptune; the Solar Eclipse at 29° Cancer activated the progressed Mercury-Pluto conjunction; the Lunar Eclipse opposed the Part of Sonia; the transiting Pluto had been squaring the Part of Sonia all year, Uranus (natally on the 4th House cusp) was crossing the natal Ascendant; and, particularly significant was the transiting Jupiter in the 7th House squared the natal 4th House Mars. Harry died of cancer.

In the chart for “Bob,” the Solar Arc IC conjunct the 6th House Pluto and Transpluto at 0 Leo; Solar Arc Jupiter conjunct the natal Moon; the Secondary Moon conjunct natal Jupiter (this man was a writer and it was the peak of his career); Solar Arc Sun-Mercury at 14 Taurus opposed the Part of Sonia; Lunar Eclipse at 13° Aquarius squared both the Solar Arc Sun-Mercury (rulers of the 4th and 7th Houses) and the Part of Sonia; the transiting Mercury (ruler of 4th House cusp) squared the Solar Arc Saturn; the Solar Arc Neptune at 13° Scorpio near Part of Sonia; the transiting Mars conjunct Solar Arc Ascendant and Secondary Uranus; the transiting Jupiter crossed the Solar Eclipse point at 29° Cancer; Jupiter conjunct (within 1 degree) Solar Arc IC and natal Pluto-Transpluto and it is inconjunct the Ascendant; the transiting Moon was conjunct the natal IC. Bob died very suddenly as a result of a congenital arterial aneurysm.

In an evaluation of all of the research charts, I found that 1) Pluto was significant in each case. This may signify the release from the physical, a release of control (death being the ultimate loss of control) and a transmutation of energy into another dimension. In the case of an auto crash, the transiting Pluto was exactly square (to the minute) the 9th House Venus. In both of the example cases, the transiting Pluto had been aspecting the Part of Sonia all year. 2) The eclipse before death was always significant. I strongly advise including both the Solar and Lunar eclipse points. 3) Jupiter was always involved at the time of death. In many cases, it was in the 7th House or inconjunct the Ascendant from either the 6th or 7th Houses. 4) The 4th and 7th Houses and their rulers were always involved. The 4th House is traditionally known for being “the end of the matter.” 5) I have found a somewhat significant occurrence of aspects from Venus and Uranus but they do not occur consistently.

Because of the high incidence involving Jupiter, the 4th and the 7th Houses, my student suggested the combination which we refer to as the Part of Sonia. With regard to the sign of Scorpio, use Pluto as the ruler and not Mars. I have also observed that this Part frequently does not work in cases of suicide or murder.

There is another pattern that I have observed wherein there is an onset of a disease followed by death. If the onset occurs when an outer planet enters a planetary configuration, often the disease is concluded just as the planet leaves the configuration. This “conclusion” could be when the individual gets well. However, I have many charts showing the onset of a terminal illness at the time when an outer planet entered a configuration such as a t-square and the individual died just as the outer planet was leaving that configuration.

In one example, an individual experienced a reoccurrence of cancer when Uranus entered his Fixed t-square. Natally, Neptune was at 22° Leo, Saturn at 23° Scorpio and Mars at 28° Aquarius. When Uranus in Scorpio entered 22°, the disease was discovered. The individual died when Uranus reached 28° Scorpio. Mars and Uranus are the rulers of the 4th and 7th Houses. The lunar eclipse before death opposed the Part of Sonia (within 2 degrees). The transiting Jupiter and Pluto squared the Eclipse Point (exact) and the Part of Sonia.

In my lecture for the Washington group, I included some timely additions. 1) Princess Diana: Solar Eclipse at death was conjunct her 8th House Mars-Pluto in Virgo and the transiting Venus was crossing the Part of Sonia while opposing the transiting Venus. Her death was more obvious in the progressed horoscope of Prince William. His progressed Mars was conjunct his progressed Saturn in the progressed 8th House. This conjunction would have been exact in November. 2) Sonny Bono: Part of Sonia at 16 Libra formed a transiting Cardinal T-Square with the Moon-Saturn in Aries and the Sun at 15 Capricorn. Neptune was crossing his 4th House North Node and the transiting North Node was crossing his 12th House Neptune. His death was obvious in Cher’s horoscope as her progressed Sun opposed her 7th House Moon and squared her 4th House Jupiter. The Sun is natally in her 11th House ruling “a death in the family circle,” being the 8th House from the 4th House. 3) John Denver: Lunar Eclipse before death opposed his Part of Sonia at 25 Virgo, the 7th House cusp at death was conjunct the Part of Sonia, the transiting Pluto made many powerful, hard aspects including a square to the progressed 8th House Sun.

After conducting my first level of research, I quickly realized that the Part of Sonia in any horoscope would be transited many times in one’s lifetime before it actually triggered one’s death. In 1990, I could not see how significant this Point was in my own horoscope since I was just beginning to experience the many changes and ultimate transformation of my life. Later, I could see that this was a Point of Transformation. If one was willing to experience great change, it would transform your life. If you could not allow this, the transformation would be death. I realize that this is the great significance of this Point – where and how great transformations are experienced in our lives.

When discussing death, I refer to this point as the Part of Sonia but, when referring to its transformative qualities, I will refer to it as the Point of Transformation.

In my own horoscope, the Point of Transformation occurs in my 7th House. In this lifetime, I will experience major transformations due to relationships and relationship issues in my life. When Uranus trined this Point, I formed a “marriage type” relationship with a man that I ultimately knew for 28 years. We first met in school when Uranus opposed this Point. From late 1986 through 1990, the outer planets transited aspects to this Point and this led to the series of events that ultimately compelled me to travel to Eastern Europe and transform my life. From the Spring 1994 through early 1995, Saturn was crossing this Point and it was the only time that I did not travel to Eastern Europe… or anywhere. I began to gain weight, I fell into a rut and felt out of control with the lack of connections in my life. In 2002, when Saturn squared this Point while crossing my Moon, my mother suddenly died.

A friend, Stephany, has this Point in her 4th House ruling ancestral patterns connected to home and family issues. When the outer planets began crossing this Point, she began studying astrology with me. This significance of this is that what she learned in the classes gave her permission to end her “good girl” relationships with her dysfunctional family. I remember her telling the class that her parents always warned them that, if they ever wanted to be happy, they must never have children. No one ever had the courage to break with this tradition… until Saturn crossed Stephany’s 4th House Point of Transformation. With the first crossing, she discovered that she was pregnant at the age of 43 years. With the exact second crossing, she gave birth to Alexandra. The birth of this baby totally transformed both Stephany and her family. She now has a good relationship with her mother who is devoted to the baby.

I will use my own chart to demonstrate how simple it is to convert the formula in the Part of Transformation. Remember, the formula for this Part is The Ruler of the 4th House Cusp + Jupiter – the 7th House Cusp. 1) I have the sign of Scorpio on my 4th House cusp. Its ruler is Pluto and it is at 10Leo40. 10 degrees of Leo converts to 130. 2) My Jupiter is at 1Libra03. 1 degree Libra converts to 181. 3) My 7th House cusp is 2Pisces37. 2 degrees Pisces converts to 332. I will omit the minutes and only use the degrees here. So, the formula is 130 + 181 (311) – 332. I cannot subtract 332 from 311 so I must add 360 to the 311 to get 671. 671-332=339. I look up 339 and it is 9 Pisces. This is my Part of Transformation. If you have trouble with the calculation, send me an e-mail. The Arc Conversion Table to which I refer can be found in Llewellyn’s A to Z Delineator.

  1. Lynn Koiner Says:

    BRIANA – Your Part of Transformation/Sonia is 13 Scorpio 44. I use Solar Fire calculator so that I do not make a mistake either. This is not easy to do without a Arc conversion table.
    Look at outer planets transits to this point to observe transformations that would impact work, school work and possibly even health. I have not observed health issues with the Part as these would only be significant if it triggered a major life transformation.
    This Point makes a sextile to Mars (use only 1 degree aspects) so that benefits usually come through this Point, since it would (usually) favorably aspect Mars at the same time.

  2. Lynn Koiner Says:

    WB (10-2011): Forget about all of these aspect to Nessu, the Nodes, Vextex and what-not. Basically, I only use conjunctions to the POT and these bring transformations in the life. Transformations are good unless one is afraid of any change.
    If you are afraid of traveling on a specific date, then do not travel. The fear alone can attract problems.

  3. Micheline Says:

    Hi, Lynne this has been one very eventful year in my life. As I live in Tokyo! The great Tohoku earthquake was a very scary and then we are still dealing with this mess in Fukushima. I just finished reading your article here. Very insightful and so interesting. I do have a question about this. I think we dialogued once here on your site and you mentioned that you have your ac in leo. I am not sure if that is right. I have mine at 23 d.
    My 4th house is ruled by both mars and pluto as it is at 12 d scorpio. So, I was wondering what is the right ruler to use for above mentioned formula for the point of sonia or tranformation. In a way it won’t make that much difference since both my mars and my pluto just happen to be in very close degrees and in a stellium in the 2nd house with uranus. What do you suggest?
    Thanks I hope you don’t mind my asking the question.
    Have a wonderful day.

  4. Lynn Koiner Says:

    MICHELINE (11-2011): Good question— I generally use the modern rulers so I would use Pluto…but you could always look at the Part using Mars. But, my first choice is Pluto.

  5. Sonya Says:

    Very new to studying astrology, I found your website while looking for information of the part of fortune; your article is really intriguing!
    Curiously, my Part of Sonia falls at 12° 9’ 13” Aries and my Part of Fortune falls at 12° 11’ 1” Aries (this is just inside my 12th House which starts at 10° 1’ 38” Aries). This part of my chart is pretty empty, no planets nearby and none in the 12th House at all. The only aspect it has is +/- square with my Sun at 10°10’34” Cancer.
    Would this occur commonly and is it of any significance in reading my chart?

  6. Lynn Koiner Says:

    SONYA (11-2011): I have never found transits to my Part of Fortune did anything. So, watch when Uranus crosses your Part of Transformation in 2014 and let us know. Do not expect it to be exact. This is a 1 year transit.

  7. Sonya Says:

    2014! Well, I guess I’ll be ready and have a much better understanding of astrology by then! Thank you so much for answering my question. :)

  8. Sheree Jacobi Says:

    I can’t figure my point of transformation. Born Dec 1, 1954 at 12:19am Oklahoma City, Oklahoma.

  9. Lynn Koiner Says:

    SHEREE (12-2011): My computerized calculator is not working. By hand, I get 18 Aquarius.

  10. Jen Says:

    I used an online Arabic parts calculator and came up with 16 Gemini… it falls between the Venus/Saturn conj. in the eighth natally. I always felt this configuration was signifigant and this makes it seem more so. My husband has Moon/Saturn conjunct in Gemini within a few degrees of my Venus/Saturn. His mother is deaf, which I find amazingly literal but I don’t have an accurate birth time for him to know for sure what the angles are. It seems we have a very karmic relationship. Just thought I’d share…

  11. Pamela Says:

    Lynn, u indicated you used solar fire calculator to calculate POS. I have solar fire gold vs. 7.1.0. I cant find the calculator in my program. how did u use solar fire?

    Here is how I calculated by hand:

    nadir = 28 taurus ruled by venus at 2 cancer
    90+2 = 92
    jupiter is 10 pices =330+10 =340

    340+92 = 432

    7th cusp = 5 leo = 120+5 = 125

    432-125 = 307 = 7 aquarius

    last question: do i use natal or progressed? if natal, shouldnt u also progress the POS?

  12. Lynn Koiner Says:

    PAMELA (7-2012): Congratulations, Pamela — your calculations are correct! I use the natal, not progressed. You can progress planets to this point, watch major transits and eclipses. I have never used the Progressed POS but you can always experiment.

    With Solar Fire, go to Utilities. At the bottom is the Arabic Parts calculator and you can make up your own here.

  13. piya Says:

    I calculated it on my friend’s chart.I had accurate dob and dod but it is not working.
    maybe it doesnt work on all.


  14. Lynn Koiner Says:

    PIYA (3-2013): You do not explain how you used it. If you used this to determine when the friend would die, you would surely be disappointed.

    It is a point of transformation. Look at the transits of Uranus – Neptune – Pluto over this point to observe important changes in the life.

    It worked for my research subjects but, as you say, maybe your friend had no changes at all and it did not work.

  15. De nova stella Says:

    Pls calculate my transformation? And how will i know if it triggers?

    4th house 19 deg 46 aquarius
    Jupiter 6 deg 38
    7th house taurus 19 deg 51

    FROM LYNN: I need the ruler of the 4th (Uranus) and the sign for Jupiter. I cannot make calculations from this. The Transformations are triggered by transits to this Point by the outer planets. You need to look at an ephemeris for this.
  16. Micheline Says:

    Hi Lynne. That trine involving my Point of Sonia 11d sag in my 4th house with transpluto at 12 d leo/12th house and uranus on Eris/9th house is starting. I really need a change!!! I am curious how to merge the 12th/9th/4th together to get a better picture on how this transformation could unfold? My natal 12th is ruled by cancer. My moon is in the 5th house in Capricorn. The. My fourth is ruled by both pluto and mars and they are inbolved i. A stellium in virgo all in my 2nd house!!!

  17. Lynn Koiner Says:

    MICHELINE (5-2013): I feel that the greater emphasis of change would be through the T Uranus conjunct Eris in the 9th House — travel, an educational experience, studies or a philosophical approach.

    This Eris transit is more about liberation from parents or a parent, family duties, and the career – generally speaking. I do not find that the Houses are all that important.

    I have a lecture on Eris but I am still giving this so it will not be until the end of this year when I post it.

  18. Ellen Says:

    Dear Lynn,

    I read somewhere that the arabic parts need to be recalculated from the Solar Return when looking at the Solar Return and what the major focus will be in the coming year. Do you or did you ever recalculate the Point of Sonia for a Solar Return or do you only work with the natal positions ?

  19. Lynn Koiner Says:

    ELLEN (5-2013): This is a good question. First, the Part of Transformation is NOT an Arabic Part. It is only positioned for the natal chart and not progressed or updated to the Solar Return.

  20. Starlove software Says:

    Very interesting, will monitor my part but it’s 1.5 degrees from a square to my natal Pluto so will be difficult to come to a conclusion.

    My take on this is, having looked quite deeply into it too, death is very hard to spot in most cases in an individual’s chart. It is however, as you noticed, often very easy to spot by looking at the things going on in relative’s lives, partners, siblings, children etc. So, the first method one should look at is family member’s charts, birth time is not required as solar arcs, progressions etc are easily visible.

  21. Lynn Koiner Says:

    STARLOVE (6-2013): This Point is not really about Death but about TRANSFORMATION. Only the outer planet transits to this Point are significant, generally, and the Conjunctions are the strongest.
    Aspects to this Point are not significant…only the House position gives clues as to the nature of the transformation…to do not worry about that square to Pluto.

    You are absolutely correct – death is easier seen in the charts of the people left behind. But, the aspects never say WHO will pass.

    Many astrologers have looked at the aspects at the time of a death and there are often easy aspects and lots of good Jupiter…because that person is going to a better place.
    The exception is found sometimes in a traumatic death, such as a car crash.

  22. Rain Says:

    May i ask what is the meaning of neptune in 6th house pisces semi square pot in 19capricorn0?

  23. Lynn Koiner Says:

    RAIN (8-2013): I have no clue. I never use the POT this way. I could work but I have never used anything but transits from the outer planets, esp. in conjunction…but a 45 degree natal aspect!
    I do not think it means anything…although I do use the minor aspects in readings when there are no major outer planet transits for that year. I have an article on the Minors on this website. Maybe the interpretation can help with the interpretation. Let us know if you find an interpretation.

  24. eflatchic Says:

    Awesome article!
    On the calculations for Part of Transformation I have two questions: I have a Virgo 4th house cusp – should I use Chiron or Mercury as it’s ruler. I’m leaning towards Chiron as it’s proving to be the true ruler of Virgo in modern astrology. What do you think?

    And also, how would one calculate if the sum of Jupiter and ruler of the 4th come to for example 488 degrees, but then you only have to subtract a small amount like 9 degrees Gemini DSC (which converted comes to 69 degrees) bringing the total to 419 – which runs over the 360 degrees to be able to figure out which sign and degree the Part of Transformation is in. Am I suppose to use the 59 extra degrees into the beginning of the cycle again bringing it to 29 Taurus? Or is there some other way I should calculate the Part of Transformation when the final total is over 360 degrees?

    Thanks Lynn :)

  25. Lynn Koiner Says:

    EFLATCHIC (11-2013): Chiron in actually in in-house comet that has not been in our solar system very long and it is not likely to stay very long in our solar system. So, it has no true rulership – it has an influence but not a true rulership.

    I use Transpluto as ruler of Virgo but, for this Part, I still use Mercury.

    When the sum is 419, subtract 360 = 59

  26. PlasticinaX Says:

    I’ve found it interesting to calculate the Path of Transformation for Hitler:
    Cusp 4th House – Capricorn, ruled by Saturn at 13º28’ (133,28);
    Jupiter at Capricorn – 8º15 (278,15)
    Cusp 7th House Aires – 26º42’ (26,42)

    133,28 + 278,15 – 26,42 = 385,01

    385,01 = 360 + 25,01

    Correct me if I’m wrong but 25 degrees of Aries is in the 15th May, right?

    It’s just curious that’s the first day of Israel as an independent country. Hitler was linked to Jewish people even after his death..

  27. Lynn Koiner Says:

    PLASTICINAX (1-2014): Congratulations as your math and calculations are excellent but the chart is wrong. Hilter was born on April 20, not May 15.

    0 Aquarius is on the 4th cusp in the published chart on Solar Fire and this would make Uranus the ruler of the 4th so the POT would be 3 Cancer 57 conjunct Transpluto.

    In terms of Transpluto in the 9th, a lot could be said for his critical putdowns of people he considered inferior only because he really felt that he was the inferior one.
    A negative Transpluto can do this.

    If you would like a copy of the chart, write to me privately at and I will send it to you.

    BUT, your calculations were done correctly for the chart that you have.

    I attend many lectures in Washington DC on this topic and I travel to Germany every year, conducting interviews. I could say so much but I hope I can write articles.

  28. Monica Says:

    Hello Lynn,
    Could you check my part of transformation calculations? I have Cancer in the cusp of the 4th – its ruler, my moon is at 20 Gemini. I have Jupiter at 9 Libra. My 7th house is at 1 Scorpio. The calculation I came up with is 28 Taurus. (DOB is 2/13/81 9:43 AM in Anaheim, CA)

    thank you!

  29. Lynn Koiner Says:

    MONICA (9-2015): Congratulations! You got it correct!

    My daughters father, my ex fiance, died as a result of a car accident. I am really new to taking astrology seriously, it has been helping me understand myself, find spirituality in astrology, which, for the first time in this life I genuinely believe is right, im gaining an understanding of my souls purpose. Its helped me deal with his death. Ive found solace in what ive so far researched into astrology and life and death. I dont know how to use your formula to see what was happening in the astrological universe at the time of his car accident, followed by his death (due to severe brain injury his life support was turned off) 4 days later. Please help me understand what was happening at these times, and why. I know its changed me. I think it was suppose to. I don’t want his death to be in vain.

  31. PO Sonia Applied Research Says:

    I’ve runs a study of a few dozen charts using this Part of Sonia calculation and I find it is a positive indicator of big transformation with possibility of death, especially with harsh aspects from Pluto/Saturn and Mars, and the touch of an eclipse or two. I have a program that runs this analysis quickly for a lifetime. But I use it discretely. Thank you for sharing.

  34. Lynn Koiner Says:

    ANGELA (5-2017): If your birth time is exact, the POT is at 14 Leo in the 11th House.

    There is a online calculator for this, which I use when Solar Fire refuses to do the calculations. I have this listed above. Do not worry that it calls it Part Of Fortune. You put in your own points and the outcome will be correct for the Part of Transformation.

    Yours was difficult for beginners because the ruler of the 4th is Jupiter and then you add Jupiter again, then subtract the 7th House cusp.
