Ophiuchus Rising

I just ran across the information that because of astronomical minutia, it may become necessary to adopt a 13th Zodiac sign called Ophiuchus. This entity is allegedly associated with the historical guy Imhotep or Aesculapius, the fellow with the snake and staff.

Also, with regard to the customary 12 other signs of the Zodiac, some dates have shifted from one sign to another. For example, yours truely will morph from a goat to an archer. I'm not sure I really mind (for a long time I thought I was a Saggitarius anyway before this change so you can see how closely I followed this astrology stuff)
