Image 57 is a spectacular close-up view of the new outbreak in the NEB(S) that began two days earlier. This is the third time that JunoCam has been lucky enough to catch one of these outbreaks in its early stages (after PJ38 and PJ39), but this one seems to be especially energetic. As in those examples, this close-up shows the bright plume as a dense white mass of pop-up clouds with hints of cyclonic spiral structure; the near edge seems to be overlaid by a red haze band. The most striking new feature is a red cloud band that completely surrounds the outbreak [completed in lo-res image 58], with closely spaced waves in its eastern part. We have seen similar red bands around apparently expanding cloud structures in some other latitudes, but not so structured.

In the adjacent EZ(N), the image shows a row of small, sharp-edged white cloud rafts, and then a long series of mesoscale waves which lie across a dark bluish festoon.
