In this study the space-time characteristics of the aurora from the all-sky cameras juxtaposes with the ionosphere irregularity distribution based on GNSS network data in the polar region. 6 GNSS stations and 4 all-sky cameras on the Kola peninsula were used. Ionosphere irregularities are determined by the RoTI level, amplitude and phase scintillations. This GNSS data were analyzed for every satellite pass and compared to the simultaneous all-sky image of the corresponding regions. The H-component magnetic field disturbance and the polar oval model also were analyzed. The data both in quiet and disturbed geomagnetic conditions were processed. The correlation between ionosphere irregularities based on radio signals from the GNSS and auroras based on optical measurements was established. This correlation can allow to detect auroras when the optical observations is obstructed. Hypothesis about the morphology of ionosphere irregularities related auroras were also proposed.
