Juno's complete rotation pre-perijove sequence, labeled
Juno's complete rotation pre-perijove sequence, labeled Before and after its first perijove on August 27, 2016, Juno’s camera was taking frequent shots of the whole planet, nicknamed ‘marble movies’. Gerald Eichstädt provided processed versions of all the raw images, which were then enhanced and annotated by John Rogers. This compilation shows the northern hemisphere, for a whole rotation in the day before perijove.

The four ovals labelled in red (WS-4, 6, 8, and LRS-1) are anticyclonic ovals in the North-North Temperate Zone (NNTZ). There are still many little round spots (vortices) on the prograding North-North Temperate Belt's (NNTB) jet. They may be induced by a large turbulent sector (‘FFR’) in the NNTB. There is also still a large turbulent (‘rifted’) sector in the North Temperate Belt (NTB), which gives rise to a darkened sector of the zone following [west of] it, the North Temperate Disturbance (NTD). Both these sectors are now of considerable length. The principal spots along the North Equatorial Belt (NEB) north edge are also unchanged: four small ‘barges’ (labelled B-1 to B-4 on the image set), and the very bright oval, White Spot Z.
