Abstract
A Pulsating Aurora Imaging Photometers System (PAIPS) is being created using observatories of the Polar Geophysical Institute on the Kola Peninsula to study the structure of pulsating auroras (PsA) in the near ultraviolet range (300—400 nm). We presented a description of two PsA cases measured by the PAIPS system together with all-sky cameras. For the first one, a frequency analysis of the signal is given and it is shown that for an hour and a half, pulsations occur at a quasi-constant frequency of about 1 Hz. For the second one, measurements of the intensity ratio in the 337 and 391 nm wavelengths are presented. An analysis of simultaneous observations of optical cameras in the field of view of the spectrometer shows that the emission in the “on” phase is “greener”, i.e., corresponds to less energetic precipitating electrons. Stereometric observations with a camera in observatory Lovozero gives the maximum correlation coefficient for the time series of cameras at altitudes of 145—150 km and ~92 km.
