Abstract
A new telescope-spectrometer was installed at Verkhnetulomsky observatory (68∘36’N, 31∘47’E) to supplement the data from all-sky cameras with measurements of the fine space–time structure of the auroral luminescence. The telescope uses 5 cm ultraviolet (UV) transparent lens as an optical system and a matrix of multi-anode photomultiplier tubes as a photo detector. The angular resolution of the telescope is 1.2∘ and the temporal resolution is 0.3 ms. The telescope observes a central part (20∘) of the all-sky camera field of view (FOV). Description of both optical instruments and results of the first joint measurements are presented.
