During this very favourable apparition, there was increased activity in several regions on Jupiter, with interesting events on both large and small scales. The most notable event was the merger of the last two great white ovals in the South Temperate region, in 2000 March, leaving a single oval which is called 'BA'. There was also a remarkable 'South Equatorial Disturbance', developing progressively during the apparition. It had a main complex manifested as a bright rift and dark bluish patch, which grew larger and larger, and a stormy sector spreading on the prograding jetstream which covered more and more of the circumference as the apparition progressed. The appearance of this disturbance was unprecedented, but dynamically it resembled great white spots seen in 1979 and 1879. The Equatorial Band and the festoons in the northern Equatorial Zone were much darker and more stable than in recent years. Dark material also appeared to be flowing off the NEBn into the North Tropical Zone. The NEB itself also appeared disturbed, both with persistent barges and bays on the north edge, and with frequent internal bright rifts.
