Results of Pulkovo plan star observations at West Spitsbergen Island

Star observations at the Bamberg zenith telescope at West Spitzbergen during 1977-1980 are a part of the Pulkovo plan for determining absolute star declinations using the zenith-symmetry method. Observational characteristics are given for polar night conditions. A total of 5500 instant latitudes were obtained for 18 months (three observational seasons). Four mean latitudes of the site are found using four programs of Talcott pair observations in different zones of zenith distances. The standard deviation of the mean latitude determined from one program is +/- 0.010 arcsec.
