    Re: Retrograde motion of the planets

    Thank you Sean C,

    I suspected that the SHA  and Aries would be involved, and in a way I suppose that they are; thank you for thinking that through. 

    I am not at all fluid in these maters but now that I have this lead I may be able to reason through it more easily.  Thank you again!

    Steve

    Steve,

    I could be wrong here, but it seems to me that it can be done this way: If one subtracts the GHA of the body from the GHA of Aries, the RA of the body is obtained. If, when subtracting the RA of a particular hour from the RA of the following hour, a negative value is obtained, then the planet is in retrograde motion.

    Cheers,

    Sean C.
