I have doubts about the meaning of "phase" in western astrology!

The angle in the astrolabe is calculated by 360 degrees of circumference. The degree formed by the connecting line between each planet and the center of the circle is the angle. A specific angle is called a phase.

For example, if the sun is in Aries 10 degree and the moon is in Gemini 10 degree, then the angle formed between them is 60 degrees, which we call sextuples.

In addition, the calculation of phase is usually not calculated by palace position, because different palace position division systems will lead to different coverage of each palace position. Only the range of constellations is equal to 30 degrees.
