Hi Bryan
The 'Magic 7' aspect is the septile series of aspects that have been used in harmonic astrology for a long time, Magi astrology certainly didn't invent it.
In my first article on the Vertex in the Analytical Techniques section on this site
http://www.noeltyl.com/techniques/050531.html I briefly covered my observations on how this aspect series worked.
From personal experience I agree that Solar Arcs can strongly activate septile aspects in the natal chart.
I have written a great deal about the septile series of aspects on various forums. Here is an extract from my 'Ask Alice' column for Southern Star, our local newletter:
"The Septile series of aspects are based on the 7th harmonic (360/7) and are made up of the septile 51'25'43', the biseptile 102'51'25" and the triseptile 154'7'08"
This aspect series describe people who are interested in 'other realities' in various ways , according to the planets making up the septile or septile pattern. It usually describes a very high level of expertise in their area of interest. These people are the seekers after wisdom.
You find septile series people in science, religion, astrology, research, psychic areas - in fact any area that could be considered deeper or more recondite to the norm for a culture. For instance I know a veterinarian who can easily communicate with most animals, reptiles and birds who has a planet conjunct his 6th house Vertex which is also involved in a big septile-biseptile-triseptile pattern in his natal chart.
Septile people are often highly inventive, especially if an outer planet is involved in the pattern. I have found a number of them involved in artificial intelligence areas.
Unlike quintile series people, septile series people tend to be quiet, sometimes shy and very modest. Usually only people involved in the same area realise the extent of their considerable abilities and skills. If they have quintiles running off one of the planets involved in the septile pattern they can be highly creative (or destructive) with their knowledge or skill.
As the septile series give the ability to understand other realities it fits well with the Vertex axis, which is a doorway to other realities, so you often find the two combined in some way in the charts of exceptional people. For example, Albert Einstein had his Vertex in Scorpio, with the ruler, Pluto, conjunct the antiVertex and in septile aspect to Mercury -Saturn. He also had a septile pattern involving Asc-Uranus-Moon. The Moon was involved in a quintile pattern made up of Moon-Jupiter-Neptune and Uranus was biquintle Mars, so he was able to become an expert in his chosen field (septile) and develop further creative/destructive use in that area (quintiles).
One of the signatures of psychic ability is a septile pattern running off the Vertex axis, though this is usually a private skill as the septile people don't enjoy publicity.
It is not unusual to have a planet in a septile series aspect to the Ascendant. In fact, it is always there in the few charts I have that I know have an absolutely accurate time of birth, so I am considering that perhaps it is a signature of the birth process. This becomes very powerful if there is an actual septile pattern involved with the Ascendant.
Septile transits are always interesting if you are looking into areas that are deeper or require specialised knowledge."

This aspect series is very important as they show people who are interested in 'other realities' in various ways - according to the planets making up the septile or septile pattern. It usually describes a very high level of expertise in their area of interest. These are the seekers after wisdom.
