A storm at the southern edge of Jupiter's northern polar region dominates this Jovian cloudscape, courtesy of NASA's Juno spacecraft. This storm is a long-lived anticyclonic spiral oval named North Temperate Little Red Spot 1 (NN-LRS-1). it has been tracked at least since 1993, and may yet be older than that. An anticyclone is defined as a weather phenomenon where winds around the storm flow in the opposite direction to that of the flow around a region of low pressure. It is the third largest anticyclonic oval on the planet, typically around 6,000 kilometers (3,700 miles) long. The color varies between red and off-white (as it is now), but this JunoCam image shows that it still has a pale reddish core within the radius of maximum wind speeds. The photograph was taken on July 10, 2017 at 6:42 p.m. PDT (9:42 p.m. EDT), as the Juno scientific spacecraft performed its seventh close flyby of the planet. The spacecraft was about 11,444 kilometers (7,111 miles) from the tops of the clouds at a latitude of 44.5 degrees.
