4 INTRODUCTION The Auroral Subcentre of World Data Centre B2 continues its publication of auroral observational data from Soviet stations in Arctic and Antarctic. Auroral data are presented by ascaplots as adopted at Moscow IAGA Assembly in September 1958 /1/. This issue contains the auroral data of 1982. The list of stations and their coordinates are enumerated in Table 1. Ascaplots for 1972-1981 were published earlier /5/. Ascaplots are the information about aurora occurence in three latitud­ inal intervals (north, zenith, south) each corresponding to three degrees of latitude. Auroral activity in the zenith region is given in a three-ball scale. The data are presented for every half-an-hour interval of observa­ tions. The ascaplots also contain the information about cloudiness and moon lighting. The methods of ascaploting are shown. Initial data from all the stations which data are used in the present issue are kept in the Auroral Subcentre. The indices of auroral activity are given for each day (Table 2). The ascaplots have been prepared by the staff of the Auroral Subcentre: L.N.Korobeynikova, N.F.Maltseva and O.V.Uschenko headed by L.N.Smirnova. The indices of auroral activity have been calculated by L.N.Smirnova.
