    Re: When did the Atumnal Equinox occure this year?

    Frank you said: Though this tool does not directly display the Sun's SHA, you can easily calculate it: SHA* = GHA* - GHAaries.

    Arn't the Sun's four SHAs going to be 360, 270, 180, and 090 automatically because of the definition of the First Point of Aries, i.e. where the ecliptic crosses the celestial equator from south to north, or should I be allowing for other effects such as mean v sidereal time.  DaveD
