N2  - Recently, Bond and Jacka (1962) sought to order the average frequency of occurrence of visible auroras in eccentric dipole latitude. It is considered that eccentric dipole co-latitudes (q''), longitudes (f'), and times for places on the surface of the Earth (here assumed spherical) may be of interest to workers in various fields. Mapped grids of q'' and f' are reproduced here.
