Ya know, what would one of those graphs look like for the equator? howbout halfway from the equator to the tropic line? howbout right on the tropic line? ooo ooo ooo, i want to see one for the north pole! I bet there's a math formula to make these.

2sin pi/364.75 (degree latitude/24cosin) = -sin/a/2

Naw, not that one, but it'll look something like that.

I leave the formula to you, Marshall.

If you go back to post:

The link will take you to where you can make any of those graphs you mention, like half way between 0 and 33⅓. Just playing with the controls will show that it is only a very limited slosh . . .

Something you can think about Marshall is sun angle. Yeah, we know that the sun doesn't rise in the winter at the North Pole. Well, in the summer it just hugs the horizon, all the way around. That makes for shadows - long summer shadows and we know that you are a student of tree shadows . (Good thing there aren't any trees at the North Pole!)

Ahhh, yes, these long days are so welcome! I love that it's light at 4 a.m.. I may be just enjoying it by looking out the window from my warm bed, but it is incredibly wonderful.
