During the luminous phenomenon of an Aurora, streams of colorful light appear as reds, greens, yellows, pinks, and purples.
Auroral arcs can stand almost still and then, as though a hand has been run along a tall curtain, begin to dance and turn.
It was truly fascinating to witness this dance against the starry sky on the shore of Lake Jääjärvi in Sevettijärvi, Lapland.
