Paper I described the normal features of the North Equatorial Belt (NEB) in recent years. This paper describes an exceptional set of apparently coordinated changes which occurred in 2011–’12, after more localised precursors in 2008 & 2010. The large dark formations on the NEB southern edge (NEBs) progressively disappeared until none remained. In the sectors of NEBs thus vacated, smaller dark features all moved with unprecedented ‘super-fast’ speeds, which were modulated by the few normal features while they lasted before accelerating further. These changes have several profound implications for understanding the dynamics of the region.
