The author of "The Sun Arc" is the modern astrologer Northal .
In his book, he mentioned: the planets in the sun arc and the planets in the natal chart form: difficult phases such as 0-degree conjunction phase, conflict phase, etc., which can be expressed by "=". SA is the sun arc, and SA Sun = Jupiter , that is, the sun in the sun arc and Jupiter in the natal chart form difficult phase.
Astrologers with many years of experience generally do not need to rely on computer scheduling. From the natal chart, they use the solar arc to calculate the approximate time of the event. Because the sun runs at a different speed in summer and winter, sometimes some degree errors need to be corrected.
And the astrological figure who translates this book is The clear sky, the moon is bright
The following are the basic meanings of each star in the propulsion of the solar arc:
HD: light, show
Mercury: Thought
HD: Elegance, love
HD: Mars : Energy, Faith
HD: Improvement, Improvement
Saturn: serious, challenge
Uranus : enhancement of personality, subversion of current state, new ideas
Neptune: confusion, ignorance, self-destruction, may bring fantasy and inspiration
Pluto : insight, huge changes, power
. Pay attention to the four axis (asc, descending, mid-sky MC, lower middle-sky), and pay attention to the outer planets.
The solar arc with greater influence is mainly the solar arc produced by the exoplanet and the four axis.
Pluto brings great changes in the outlook on life, as well as changes and subversion in various senses. If the case is still a child, the impact of this solar arc may be reflected in the parents, such as huge family changes, moving to farther places, deaths of family members, major changes in parents' outlook on life, etc.
Nehn represents confusion, depression, and weakness, and also represents imagination, fantasy, and inspiration.
Uranus is a discordant voice surrounding personal situation, often related to failed plans, acquisition or loss, independence or retreat, etc. The most important influence lies in the changes and rebirth of outlook on life and values.
Saturn represents ambition, ambition, controlled strategies, structural reorganization, or death events that may affect life planning.
Zhongtian and Xiazhongtian mainly represent parents in childhood, and Zhongtian represents his own career (including career change, promotion, entrepreneurship, dissatisfaction with the company who became a entrepreneurial motivation). Xiazhongtian is related to family and residence (including moving, real estate and furniture transactions, and "new beginnings").
Asclimbing and falling represents the self and the awareness of the self, and also represents the health and parental status in childhood. It should be noted that the rise and fall are linked, so all personal-related situations will affect people, spouses, partners, etc.
2. The solar arc is used to determine the approximate time period, and the current year and the second limit determine the specific time. The second limit method can look at the short-term fortune.
The influence of the solar arc is roughly one year, and the power in the first six months is greater than the last six months. The precise excitation of core events is often accomplished by faster running parameters, such as the second limit of the moon and the moving planet.
3. When the solar arc advancement forms more than one phase in the natal chart, it often represents the occurrence of major events.
. The solar arc in childhood (such as under 14 years old) has a very important impact on the formation of personality.
. The solar arc phase is unidirectional.
For example, SA Mercury = Saturn, which is different from SA Saturn = Mercury.SA Saturn = Mercury brings control of the mind and possible frustration. In the long run, knowledge and wisdom will be gained from persistent efforts, and from taking responsibility to mature; while SA Mercury = Saturn means using the mind to work, formulate and execute plans, work hard, carefully analyze, think about strategies, etc.
Another example is that SA Saturn = Venus leads to a sense of depression in love, falls in love with people much older than yourself, learns to trust each other in love, and strives to understand peace and calmness; while SA Venus = Saturn brings a sense of elegance to ambitions and ambitions, suddenly discovers the charm of art, and may even lose love.
3. Not everyone responds to every solar arc phase. The support of the external environment is a necessary condition for the solar arc phase to exert its influence.
For example, SA Venus = Zhongtian represents love or childbirth, but this can only happen to people of the right age. Even if a baby encounters such a sun arc, it is impossible for him to fall in love or have a child. In fact, the solar arc phase generated at a very young age often corresponds to parents or family.
So, sometimes when using the solar arc, you have to rely on worldly experience and cognition.
4. Example of solar arc push: Queen Victoria

does not eject the sun arc. From the astral disk , the mc zenith is located at 29°35', and the distance from Jupiter is 25'+16°55'=17°20'
is SAmc=Jupiter, which means that she will receive great honors when she is about 17 years old. Since the sun is running slowly in summer, our ejection error is about 0.5°.

From the perspective of the secondary limit, sp moon = mid-sky, which is a good phase.

837, the annual star TR Jupiter = Jupiter. When the second limit Jupiter and Jupiter form a phase, they will also receive great honors.
Victoria was crowned queen on June 20, 1837, 18 years and 1 month.
The second case Obama

Let’s first look at his natal chart: the more dazzling one is the civil structure. Saturn is the main star, and its state is quite good. The akabit system shows that Saturn falls in the life house and merges with the first auspicious star Jupiter.
Saturn is in the life house and has also written that his childhood life is quite miserable, and this Saturn is retrograde. Obama probably has an unhappy childhood. If you are interested, you can search for his childhood experience.
The first structure is the convergence of earth and wood, and Jupiter is the third lord, which means that Obama has a very good eloquence
The second structure is that the sun and the moon are mixed with the tenth lord, which means that his career is also very good
There are many other structures.
Let's take a look at the sun arc where he ran for president: November 4, 2008

a was surprised:
sa sun = sun
sa moon = moon
sa moon = moon
sa Mercury = Mercury
. . . . .
mentioned in the solar arc: When the solar arc advances to form more than one phase in the natal chart, it often represents the occurrence of major events.
