    Sundog

    There was a very bright sundog yesterday at sunset here. Photo linked.

    Here's a little navigation puzzle: you're walking in a hilly area near sunset on February 10 in latitude 41 N. You see a sundog about 5 degrees high directly ahead of you but you can't see the Sun (behind a hill to your left). In what direction are you walking?
