A striking display of the aurora borealis was seen on AWIPS images of Suomi NPP VIIRS 0.7 µm Day/Night Band data across Alaska (above) and across northern Canada (below) during the night-time (pre-dawn) hours on 17 December 2012. The corresponding VIIRS 11.45 µm IR channel images are also shown, to help distinguish cloud features (colder green to yellow to red color enhancedment) from the bright aurora signature on the Day/Night Band images.
