The opposition of Jupiter, 1959
2025 June 10
The opposition of 1959 immediately followed a major South Equatorial Belt (SEB) Revival. The Red Spot Hollow (RSH) persisted throughout 1959, with the Red Spot invisible and the Hollow poorly contrasted against a dusky S. Tropical Zone (STropZ). The SEB S. component faded after opposition, while the SEB(N) contained slow-moving dark sections. A notable feature was the strong reddish or orange coloration that extended from the NEB across the Equatorial Zone (EZ), SEB and STropZ. In May, the EZ coloration began to disappear, and the zone brightened slightly, but the STropZ coloration and duskiness persisted longer. As in 1950 and 1953–’54, a small, near-stationary dark spot at the N. edge of the SEB(S) preceded the RSH. The North Equatorial Current did not exhibit any slowing down. The North Equatorial Belt had widened to the north, so that the prominent light and dark spots moving in the North Tropical Current lay completely within its confines. The North Temperate Belt was nearly invisible, as in 1956–’57 and 1958. Long-enduring South Temperate white ovals FA and BC had approached each other so closely that by opposition their edges were only 18 degrees apart, and a light area (a South Temperate Belt ‘miniature’ fade) had developed between them. This report fills another gap in the BAA series and includes previously unpublished photographs as well as accurate belt latitudes.
