"White Spot Z" is one of the long-lived storms in Jupiter's atmosphere. Three JunoCam images from Juno's 21st close pass by Jupiter have been mosaicked together, showing the setting of this oval-shaped storm perched just above the reddish-brown North Equatorial Belt. This mosaic covers planetographic latitude from about 11 degrees to 23 degrees north.
Citizen scientist Björn Jónsson created this enhanced color mosaic using images from the JunoCam camera. The images were taken with a two-minute separation, starting on July 21, 2019 at 8:05 p.m. PDT (11:05 p.m. EDT). The spacecraft was at an altitude of approximately 4,900 to 5,600 miles (7,900 kilometers to 9,000 kilometers) above Jupiter's cloud tops, so features as small as 6 kilometers can be resolved in the images.
