On March 18, 2017, auroras drew an arc across the sky over Mac Robertson Land in East Antarctica. The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this view of the aurora australis, or “southern lights,” that night.

The VIIRS “day-night band” detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe signals such as gas flares, auroras, wildfires, city lights, and reflected moonlight.
