FireSignLogic, I relocated your transits chart to the

Pluto Transits Board, where I had originally intended to post it. All of the lines in any astrological chart represent

*planetary aspects*--the numerical relationship (in degrees) between different planets and/or angles.

It is common knowledge that a circle consists of 360 degrees, but did you know that this measurement has its origns in astrology, when the ancients believed a year to contain 360 days and assigned one degree to each day?

Anyway, depending into how many "pieces" or "parts" you wish to divide a circle, each segment will contain a certain number of degrees.

A full circle contains 360 degrees.

If a circle is divided into two parts, each will contain 180 degrees. This is equivalent to an

__opposition__--a relationship between two or more planets located

__180 degrees__ away from each other. It is also known as the Second Harmonic.

If a circle is divided into three parts, each will contain 120 degrees. This is equivalent to a

__trine__--a relationship between two or more planets located

__120 degrees__ away from each other. It is also known as the Third Harmonic.

If a circle is divided into four parts, each will contain 90 degrees. This is equivalent to a

__square__--a relationship between two or more planets located

__90 degrees__ away from each other. It is also known as the Fourth Harmonic.

If a circle is divided into five parts, each will contain 72 degrees. This is equivalent to a

__quintile__--a relationship between two or more planets located

__72 degrees__ away from each other. It is also known as the Fifth Harmonic.

If a circle is divided into six parts, each will contain 60 degrees. This is equivalent to a

__sextile__--a relationship between two or more planets located

__60 degrees__ away from each other. It is also known as the Sixth Harmonic.

If a circle is divided into seven parts, each will contain approximately 51.5 degrees. This is equivalent to a

__septile__--a relationship between two or more planets located approximately

__51.5 degrees__ away from each other. It is also known as the Seventh Harmonic.

If a circle is divided into eight parts, each will contain 45 degrees. This is equivalent to a

__semisquare__--a relationship between two or more planets located

__45 degrees__ away from each other. It is also known as the Eigth Harmonic.

If a circle is divided into nine parts, each will contain 40 degrees. This is equivalent to a

__novile__--a relationship between two or more planets located

__40 degrees__ away from each other. It is also known as the Ninth Harmonic.

If a circle is divided into ten parts, each will contain 36 degrees. This is equivalent to a

__semi-quintile__ or

__decile__--a relationship between two or more planets located

__36 degrees__ away from each other. It is also known as the Tenth Harmonic.

This can be continued for an infinite number of harmonics...

I hope this helps!

EDIT: I should probably mention that the "harmonious aspects" (trines and sextiles) appear as blue lines in most Astrodienst-generated natal charts, while the "difficult aspects" (oppositions and squares) appear as red lines. Quincuxes, commonly known as inconjuncts, appear as green dotted lines; the other aspects are not as widely used and therefore do not appear on most natal charts.
