Northern Lights in Motion. Reworked previous sequences and added music. Northern Lights Time Lapse photography illustrating movement of Northern Lights some 50 to 100 miles high in the sky.

However, a few are channeled by earths magnetic field into curtain like structures. Northern Lights are usually green, but at higher latitudes, red and purple can be seen dancing in the sky.
