High-aperture instruments are required for the airglow measurements. No specialized equipment is made for this purpose at the moment. Some foreign manufacturers make patrol spectrometers for registration of the spectral composition of auroras. However, their sensitivity is not enough to work with good time resolution in the mid-latitudes and to study fast processes in the auroral radiation of the upper atmosphere, for example, the spectral composition of optical flashes. The aim of the work was to select modern equipment and evaluate its efficiency for registration of the spectral composition of optical radiation of the Earth's upper atmosphere in the middle and high latitudes. Shamrock SR-303i universal spectrograph has been selected to study the possibility of airglow measurements. The device was tested in a quiet geomagnetic condition and during a severe geomagnetic storm of March 17, 2015. The capability of Shamrock SR-303i to register a mid-latitude airglow in undisturbed conditions and during the mid-latitude auroras was demonstrated.
Keywords: atmospheric emission, spectrometer, geomagnetic storm
