memo to self

The sun sets these days at about ten 'til six, and it takes at least twenty minutes to walk around the lake to the east beach, and thirty to amble.

Good point. That makes more of a difference than I give it credit for sometimes. (Can you tell I don't travel much? :-) )

By definition, the east-west span for sunrise/sunset times is just a hair under 60 minutes, depending on where along that span you are. I wonder what the north-south span is, ignoring places that don't have daily sunrise/sunset.

I have no working intuition on this, so I asked the Army again. Makes several hours difference (this time of year) as you go north from Seattle, about an hour as you go south:

arctic (W 122, N 78): 2:22 p.m. (all times PDT)
Seattle (W 122.4, N 47.6): 6:05 p.m.
San Francisco (W 122.4, N 37.8 (3 degrees south of Pgh)): 6:21 p.m.
equator (W 122, N 0): 6:56 p.m.
