The mean Saturnicentric latitudes of the NTBc, NEBn, and NEBs (see Table 3 footnotes for a description of the nomenclature) determined by the BAA for the seven oppositions between 1980 and 1986 are 40[degrees], 25[degrees], and 12[degrees]N, respectively (Heath, 1981, 1984, 1985b, 1985c, 1986, 1987, 1989), whereas Voyager I and II images show latitudes of 36[degrees], 20[degrees], and 5[degrees]N, respectively (Hollis, 1985a); finally, the photographs of Saturn made on 3 July 1989 (Di Cicco and Robinson, 1989) carefully were measured by me and suggest Saturnicentric latitudes of 38[degrees], 21[degrees], and 9[degrees] for these three features.
