Introduction

As probably anyone who reads my blog knows, I have recently done a few blog posts related to astrology, specifically criticizing the astrologer Terry Nazon, both for her bad astronomy and for her threats and harassment towards me. My friend and much more famous anti-astrologer Phil Plait was even kind enough to mention me on his blog, though I’ll admit that I did point out my problems with Ms. Nazon.

This post is not about Ms. Nazon. This post is about astrology in general, and specifically whether my criticisms have been fair given that astrologers – some Western astrologers, anyway – use a different coordinate system and different definitions than the world’s astronomers.
