Aurora australis, Bluff Harbour

Aurora australis, Bluff Harbour

The southern lights or aurora australis are often seen in the skies above southern New Zealand. This blue-green curtain of luminescent light was photographed above Bluff Harbour. An aurora is formed when charged particles streaming out from the surface of the sun are drawn toward the magnetic poles of earth. They collide with atoms in the upper atmosphere, causing them to emit light energy.
