Using the “day-night band” (DNB, 505 to 890 nanometres – primarily visible light from green to near visible infrared) of the <a href="https://en.wikipedia.org/wiki/Visible_Infrared_Imaging_Radiometer_Suite" class="extiw" title="w:Visible Infrared Imaging Radiometer Suite">Visible Infrared Imaging Radiometer Suite</a> (VIIRS), the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite acquired this view of the aurora borealis early on the morning of October 8, 2012. The northern lights stretch across Canada’s Quebec and Ontario provinces in the image, and are part of the auroral oval that expanded to middle latitudes because of a geomagnetic storm.
