Strange lunar halo with an excessive lower tangent arc

This photo was taken on 28.10.2015 at 10:10 p.m (local time) near the Swedish city Tärnabi – a birthplace of the famous Swedish skiers Ingemar Stenmark and Anja Pärson (65° 43' N; 15° 18' E). It is a full lunar halo with clear parhelic circle and upper and lower tangent arcs. The latest one is the glow over the road. The explanation of this phenomenon is following: in an absolutely clear night and almost full moon, multiple machines were making artificial snow the ski pistes of Tärnabi. Billions of crystals ejected from the machines is responsible for this show. The image above was taken using my Canon 60 Da camera with 10mm lens. The exposure time was 0.6 sec at 3200 ISO. Hovering the mouse over the image will show the names and position of the different atmospheric phenomenons, as well as an annotation map of the background sky.
