Overnight View of Hurricane Sandy

This image of Hurricane Sandy was acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite around 2:42 a.m. Eastern Daylight Time (06:42 Universal Time) on October 28, 2012.
The storm was captured by a special “day-night band,” which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as auroras, airglow, gas flares, city lights, and reflected moonlight. In this case, the cloud tops were lit by the nearly full Moon (full occurs on October 29). Some city lights in Florida and Georgia are also visible amidst the clouds.
The Suomi NPP satellite was launched one year ago today (on October 28, 2011) to extend and enhance long-term records of key environmental data monitored by NASA, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Department of Defense.
