I took this photograph on 15 September, and you can hardly even see the tree, or much else, because I got so caught up with the sunset.  Anyway, it’s the same tree that I photographed on 10 September last year, the one that marks for me the beginning of autumn.  I think we decided then that it’s a spisslønn, Acer platanoides. the Norway maple, not to be confused with Acer pseudoplatanus, the sycamore tree.
