[Aztlan] Aztlan: Solstice Sunrise Locations

[Lawrence Poulsen]

Computer astronomy programs such as Starry Night allow you to check the 
position of the sun at any time in the past and future from any position on 
the earth. They take into account all of the changes in precession over 
time. Contact me off list if you want more info.
