    John Karl, you asked:
    "To understand the Lord Ellenborough trick, It seems that I need to know what the Pole of a great circle is. I've never come across this term,"

    Sorry, I thought it was self-explanatory from the description. I see that Andres and George have explained. Every great circle has two poles. They are the points 90 degrees away from every point on the circle.

    And:
    "Also, what do the two asterisks mean (as in *pole*)?"

    It's an old "Internet-ism". It just means emphasis. If I were writing in fully-formatted text, I would have used italics.
