Apparent Magnitude and Absolute Magnitude

[glaucus]

If most astrologers are using ecliptic longitude projections, then why does Apparent Magnitude of the stars matter? Magnitude that is mentioned in Astrology in regards to number referring to brightness is really Apparent Magnitude which is a measure of its brightness as seen by an observer on Earth. This is also referred to as Visual Magnitude. There is another type of Magnitude. It is Absolute magnitude is a measure of the luminosity of a celestial object, on a logarithmic astronomical magnitude scale. The Apparent Magnitude makes sense in Bernadette Brady's Visual Astrology that includes the use of parans, but it doensn't make sense in an Astrological system that includes of projecting stars onto the ecliptic which has no visual basis. Why not use Apparent Magnitude with ecliptic longitude projections?



Sirius is the brightest non-solar system star in, but it's far less luminous than many stars including those with extremely high Visual Magnitudes. Sirius' Apparent Magnitude is - 1.46, and its Absolute Magnitude is 1.4.

RW Cephei is an orange hypergiant star in the constellation Cepheus. Its Apparent Magnitude is 6.52, and its Absolute Magnitude is -9.11. Sirius is far brighter than RW Cephei from the perspective of the oberver on Earth, but RW is way far more luminous than Sirius which appears brighter because of its proximity from Earth.

glaucus, I'm not sure if I understand this. How does this affect people? Has there been any research on how the magnitudes manifest in their influence? I expect not since the influence of stars is relatively unexplored and discussed. For beginners (like me), magnitudes I think are a nuance too far to grapple with.

There are astrologers that have based their orbs off the Apparent Magnitude of the specific star. I have seen it in Vivian Robson's book. I have seen it at Anne Wright's site. I have seen it at Jamie Partridge's site. With these astrologers using longitude ecliptic projections, why bother with their Apparent Magnitude?

Even though Brady practices a Visual Astrology with her use of parans involving the horizon coordinates, she doesn't put importance on the Apparent Magnitude of the stars. She puts importance on the richness of their mythologies. She refers to such stars as mythologically bright.
