Odd Shadows
Friday, August 03, 2007
So I was talking a walk a while ago through Salem and I noticed that, as I was walking east along Center St. NE near 25th St at about 8:00 in the evening, I was casting a shadow to the southeast. Now this seemed rather peculiar to me, since, although I was just south of the 45th Parallel (by maybe 3 miles), I was significantly north of the Tropic of Cancer.
The view west from where I was standing. Note that the appears on the right-hand side (northern side) of the street:
And a view to the east from where I was standing, looking along Center St NE. Notice the shadows cast significantly to the southeast.
Now I understand the Earth's axial tilt and seasons and so on, but it never occurred to me that, being roughly halfway between the north pole and the equator, I'd ever see light coming in from the north.
So I thought I'd check it out. On both a real globe and Google Earth I rotated the Earth around so that Salem was approximately where it would be at 8:00 PM... but I still didn't see how I could be casting a shadow that far to the southeast. Perhaps I didn't do it entirely correctly, but it seems odd that it would be that noticeable here.
Can anyone explain it to me?

Glitch in the Matrix. Nothing to see here, move along.
"Can anyone explain it to me?"
I certainly can't. Cripes, you had me confused at axial tilt.
