February 1, 2019 – A giant, spiraling storm in Jupiter’s southern hemisphere is captured in this animation from NASA’s Juno spacecraft. The storm is approximately 5,000 miles (8,000 kilometers) across, or roughly the width of the United States.
The counterclockwise motion of the storm, called Oval BA, is clearly on display. A similar rotation can be seen in the famous Great Red Spot at the top of the animation.
Juno took the nine images used to produce this movie sequence on Dec. 21, between 9:24 a.m. PST (12:24 p.m. EST) and 10:07 a.m. PST (1:07 p.m. EST). At the time the images were taken, the spacecraft was between approximately 15,400 miles (24,800 kilometers) and 60,700 miles (97,700 kilometers) from the planet’s cloud tops above southern latitudes spanning about 36 to 74 degrees.
Citizen scientists Gerald Eichstädt and Seán Doran created this animation using data from the spacecraft’s JunoCam imager.
