Today’s Image of the Day from NASA Earth Observatory shows the location of an unexpected aurora that was visible across parts of North America in August 2018.

For over 12 hours, green and purple lights could be seen dancing around the sky, and the activity was captured by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite.

The light emissions were detected by the satellite’s “day-night band” (DNB), as energetic particles fell from a geomagnetic storm into the upper atmosphere.

This image was captured over Quebec, Canada, in the early morning hours of August 27.
