South South Temperate Belt SSTB South Temperate Zone STeZ South Temperate Belt STB South Tropical Zone STrZ South Equatorial Belt SEB Equatorial Zone EZ North Equatorial Belt NEB North Tropical Zone NTrZ North Temperate Belt NTB North Temperate Zone NTeZ North North Temperate Belt NNTB North North Temperate Zone NNTZ North Polar Region NPR 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: DARK MARKINGS (D) BRIGHT MARKINGS (W) Darker section of belt (sect.): Oval: Condensation (cond.): Nodule: Elong. cond.: Bay: Rod : Notch: Projection (proj.): low: Gap: tall: Rift: Veil (or Shading): Streak: Festoon (fest.): Patch: Loop fest.: (or Garland) Other common abbreviations: Column (col.): v=very, L=large, Sm.=small, conspic.= conspicuous, indef.=indefinite, RS=Red Disturbance (Dist.): Spot, RSH=Red Spot Hollow, ft=faint, ?= timing uncertain, est.=estimated.
