NOMENCLATURE

     Belts and Zones. The following nomenclature. and abbreviations are generally
accepted among Jupiter observers. It should be noted that during a given apparition not
all the belts and. zones shown in the diagram may be visible. Also, more belts may be
detectable north of the NNTB (or south of the SSTB); these should be designated NNNTB,
etc. North and south components of a divided, belt are indicated by Nan, NEBs, etc.

     Surface Features. The following nomenclature, proposed by Budine and Reese in 1960
(Strolling Astronomer, Vol. 14, p.p.18-21), has been found extremely useful:
