Sunny Day Feels Like February

Now that we got -20°C I can say it feels like winter. But as I was riding about I somehow got the feeling that it was like in February. I guess it is the increase in sunlight and the cold temperatures that makes me feel so. But just look at these pictures: there's hardly any snow and it's late January. Weird.

When I was taking these pictures in the park I got the idea to take a picture of the long shadows. Well the shadows cast by the trees and such were too tall for my purposes, so I had to find a twig and stick it in the snow. Then I realized the twig wasn't very visible (no leaves :-) so I stuck a piece of paper on it. Hmm, white paper and white snow...? Look for the footsteps in the middle and you might notice it.
A few minutes with Gimp to add some lines to show the plot. Gimp has a measuring tool which gives the angle as 5 degrees. Sun was  5 degrees above horizon at after 1pm. Copying files around lost the timestamp so the time is inaccurate at the moment. But maybe someone can calculate the time if he knows sun was 5 degrees high, Oulu lies 65 degrees north. :-)
