Auroral Substorm from Polar

This movie is an auroral substorm event observed by the visible light camera aboard the Polar spacecraft.

Because the visible light camera records in a single broad range of wavelengths, we do not have color imagery of the event. For this movie we will color the aurora green since that is the dominant color in most cases. The VIS camera is also low resolution so the fine aurora details visible from the ground are not apparent in this movie.

This movie is an aurora with a substorm event observed by Polar.    This movie is an aurora with a substorm event observed by Polar.
