Visibility IV / V
I first saw the night clouds as a kpton at 11.30pm. At the first observation point in Akaan Kylmäkoski, I was just before midnight. The play was then at its widest, from west to east and 35 degrees high, the best pieces at that point in the north (Fig. 2). I changed the observation site to Urjala (Figures 3,4 and 5). Great bright play, no more scope. At the end of the night I drove to Akaas beach, for the first time this summer the water surface was completely calm, yes it was beautiful to see (picture 1.).
