Dirk and me visited our friend Robin in Helsinki in the beginning of January 2003. Of course we wanted to skate, preferably on the sea, but it was not possible with the frozen snow on the sea. Instead we did a hike on the sea. During this hike we saw this clear sundog with a near to be halo. Sundogs and halos are formed by ice crystals in the air and can appear during wintertime when the sun stands low.
