Hurricane Isaac at Night

Early on August 29, 2012, the Visible Infrared Imaging Radiometer Suite on the Suomi-NPP satellite captured this nighttime view of Hurricane Isaac and the cities near the Gulf Coast of the United States. The image was acquired at 1:57 a.m. local time by the VIIRS "day-night band," which detects light in a range of wavelengths from green to near-infrared and uses light intensification to enable the detection of dim signals. In this case, the clouds of Isaac were lit by moonlight.
