. Infrared images of Uranus (1.6 and 2.2 microns) obtained August 6, 2014, with adaptive optics on the 10-meter Keck telescope. The white spot is an extremely large storm that was brighter than any feature ever recorded on the planet in the 2.2 micron band. The cloud rotating into view at the lower-right limb grew into the large storm that was seen by amateur astronomers at visible wavelengths. Imke de Pater (UC Berkeley) Keck Observatory images
