With the GRS in transit Ganymede and Io were on each side of the planet, both moving from right to left in this image so on the near side of Jupiter, which is shown south up. The seeing was again excellent which means that the resolution of the cloud formations on Jupiter and the surface features of the moons was very good.
The dark maroon coloured band continues to encircle the GRS, although it is perhaps thinning. There is an interesting light coloured and almost linear formation within the Red Spot Hollow (RSH), which shows its characteristic light green hue.
The large white oval feature at the very north of the NEB maintains its relatively steady position north of the GRS.
