The precipitations of energetic electrons observed at the Spitsbergen latitude, which manifest themselves in the optical range as auroras, differ in their origin and morphology from the precipitations in other regions of the auroral zone. The electron energy determines the height of the auroral luminescence, which in the experiment can be determined from triangulation observations. In 2018, optical devices of the Polar Geophysical Institute on the Spitsbergen archipelago were supplemented with an additionalcamera. The camera is installed in the Barentsburg settlement, 4 km southern of the main optical pavilion and has a field of view of about 30 degrees. In patrol mode, the camera is directed to the zenith, which allows, together with the data of the all-sky camera, located in the main optical pavilion, to obtain information about the height of the observed structures of auroras in the vicinity of the zenith. The report contains the parameters of the optical system used for triangulation and examples of the registration of auroral structures.
