Quincunx or the 150 degree aspect:
According to Donna Cunningham-
"From years of observing the quincunx (150-degree aspect) in action, I have a sense that the keyword for it is "stretching." When two planets are quincunx by sign, their basic natures are so completely different that the only way they can connect is a stretch, maybe a creative leap. This produces an expansion of perspectives, and so quincunxes wind up helping us grow in a way that a square or opposition does not—it’s not a conflict as much as it is an evolution."
Gosh... not sure... the quincunx (and by extension the Yod formation) is not something I have been able to get a real grip on. My first thought on the matter is that the various points/signs/planets HAVE TO find some common meeting ground. They are not the most natural bedfellows but have to find medium by which they can relate and cooperate and be creative.
With regards to the Yod, Robert Hand suggests thinking of it as a midpoint combo.
I'm not sure. Hopefully somebody with a more fully formed opinion will have something to offer.
I have a thread here that should be of interst
I interpret the quincunx as a lesser or moderate "hard" aspect. In the grand scheme of things -
Strongest aspects - conjunction (soft) and opposition (hard)
Major aspects - trine (soft) and square (hard)
Minor aspects - sextile (soft) and quincunx (hard)
The quincunx makes the most sense when you look at it alongside the other hard aspects. So I'll explain/interpret all three.
Opposition - strongest aspect. The energies of the two planets are in direct opposition to each other, and they interact in such a way that each planet fundamentally alters the energy of the other. This opposition isn't necessarily "bad" in the sense that it is harmful or evil - it's simply that the energies of the planets work against each other. The planets may each moderate what would be excessive influence from the other, or they may "cancel out" just like radio waves cancel each other out. The point is that in an opposition, the interaction of the planets involved has an effect on the basic nature of the planets, and spills over to any and all other aspects in which the two opposed planets are aligned.
Square - strong aspect. Two planets square to each other represent planetary energies which are actively at work against each other. These represent obstacles and challenges that you deal with on a daily basis. Square planets are always active; you don't have to "trigger" them. Their energy is active on a regular basis and must be dealt with accordingly. Again, the energies working against each other may not be "bad," but it does represent a challenge to you. As long as you are invoking the energy of one planet in the square, you will always have to deal with the opposing energy of the other. But in a square, each of the planets remains "pure" in its energy. Unlike a conjunction, two planets in square don't fundamentally alter and shape each other's energy.
Quincunx - moderate aspect. Two planets in quincunx represent the more "passive" type of opposition. The energies of the planets in quincunx is not actively at work in your daily life - but it's a potential, like a trap that has been set but hasn't been sprung. When you invoke the energy of one planet, it "triggers" the energy of the other planet, which works in opposition to the energy that you are trying to draw upon.
In this way, the quincunx is particularly dangerous, because its interaction can be unexpected and unpredictable. Quincunxes represent potential challenges, ones that you aren't aware of - YET. It's important to be aware of your quincunxes so you can anticipate them. It's even possible to turn them to your advantage.
For example, let's say you have Mars quincunx Mercury. In a negative or harmful sense, this can be a problem for you because when you invoke the energy of Mars - decision, assertion, action, forward progress - you will accidentally trigger the energy of Mercury to work against you. This might manifest itself in the form of second-guessing your decisions, or over-thinking things to the point where you find yourself unable to make a decision or choose between alternatives. It's not that the analytical, thinking energy of Mercury is "bad" - it is simply working against the Mars energy that you are trying to use.
If you are aware of this potential "trap," you can turn it to your advantage. When you have an important decision ahead of you, do your thinking and analyzing FIRST. Invoke the intellectual energy of Mercury, and expect in advance that Mars will kick in, acting in a way that will work against your Mercury energy. When you "use" the quincunx this way, for example, you can keep yourself from being paralyzed by overthinking things, because as soon as you trigger your Mercury energy, you are expecting Mars to kick in and push you toward decisive action. Just be careful not to let the quincunx Mars energy drive you to decision and action TOO soon. If you know in advance that invoking Mercury will also trigger Mars, then you can anticipate the interaction and prepare for it.
Hopefully that helps you make more sense of the quincunx. This may not be "textbook definition," but in my years of doing astrology work, this is a functional definition that seems to work very accurately for me in my chart interpretations.
I'd love to see your quincunx ;-) That was awesome!
Thanks for the fantastic post! I've been trying to catch up a bit on this forum, after being absent for ages, and I'm really enjoying and getting a lot out of your posts. That description of the opposition was fascinating; I was really intrigued by the idea that planets involved in an opposition fundamentally alter the energy of each other.
It was great to read your description of the quincunx, too, because I'm always a bit foggy when trying to interpret/understand quincunxes. It helps me to think about the two planets involved as coming from completely different places to the point where they have a hard time relating (different element and modality), and that seems to make sense with your description of the conflict between planets in a quincunx as being more 'passive' than that of a square or opposition... and able to catch a person more off-guard when triggered.
I always have a hard time using this idea practically and interpreting actual quincunxes, though, when looking at my own chart, because I have two of my tightest aspect formations involving Pluto and Neptune (which are in a generational sextile in my chart). I have my Sun opposing Pluto and trining Neptune, making one formation, and my Ascendant quincunxing both Pluto and Neptune, making the other. Since both the Sun and Ascendant have some dealing in self-expression, I think weeding out the effects of each aspect formation proves especially tricky for me. I will say, though, that ego expression (while internally massively inflating or completely shredding my ego) is one of the most difficult issues for me in a way that seems very much linked to my Sun-Pluto opposition. And that I feel most like myself when I'm alone in a crowd, which might be Sun-Neptune. And that I'm unreliably able to self-express - sometimes I can quite well, sometimes I can't at all... which I thought might have been a Gemini Ascendant issue, but might also be an Ascendant/Neptune/Pluto issue. It IS like when I try to self-express, I am not sure what to expect, even though I'm a pretty cautious, contained person, overall (AND even though I have a very self-censoring Ascendant-Saturn opposition). Maybe I need to figure out how to plan for the Pluto and Neptune triggers.
With the Quncunx two things are related but it is not an obvious connection. The Elements and the Modes are not connected, yet somehow there is a relationship between two seemingly diverse parts of the persons character. As in driving you are used to cars next to you and approaching head on to you or from the cross roads but this is a place (150 degrees) you would not look for another car.
