A prominent bluish-gray plateau with a trailing festoon can be seen on the south edge of the NEB. The northern edge of the NEB is very uneven. South is up. (Credit: Cristian Fattinnanzi).
Fig. 3.29. Jupiter with a very quiet SPR on February 10, 2004. Note the absence of any remarkable features in the region.
