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, fires, and reflected moonlight. In this case, the cloud tops were lit by the full Moon. Some city lights in North Carolina and South Carolina are also visible through the clouds.
