The halo season has started in the Czech Republic, too. The above image was shot by Jiri Papez on 13 December in Dvoracky ski center. Nearby on Lysa hora the display was captured by the Hydronet.cz camera ( 1 ).

This display was photographed on 4th December by Liisa Eronen in Kulho, Kontiolahti, Finland. The temperature was around -4°C. Nearest ski center is located about 10 km away, so most likely this was caused by snow guns.
