Aurora Borealis, Norway.

1 pieces

The aurora over northern Norway comes in green most often, with red and violet when the activity is strong, moving across the sky in curtains that fold and unfold faster than people expect. It needs a clear night and dark, and the best months are the coldest ones, seen from a fjord shore or a mountain with snow on it. The colours come from oxygen and nitrogen high in the atmosphere being struck by the solar wind. The pieces here come as prints, ornaments and more.
