“…High sensitivity and spatial resolution are ensured by the use of a matrix of multianode photomultiplier tubes (MAPMTs) operating in the photon counting mode and the area of the optical system (20 cm 2 for VTL and almost 500 cm 2 for LOZ). A more detailed description of the equipment can be found in [21,22].…”

Spectroscopic measurements of aurora emissions provide valuable insights into the altitude of electron atmospheric penetration and their maximum energy. To achieve this, the photometers used in the PAIPS (Pulsating Aurora Imaging Photometers System) project are equipped with spectrometers. These spectrometers enable the measurement of auroral emissions in narrow spectral lines with a temporal resolution of milliseconds. In this study, we present two cases of PsA (Pulsating Aurora) measurements in the 337 nm and 391 nm spectral lines. We demonstrate that during quiet geomagnetic conditions the ratio of night sky emissions in these bands is close to one and significantly increases during substorms. We propose and implement a special procedure for estimating this ratio. Our findings reveal that the intensity of emissions in both spectral lines correlates with the AL index of geomagnetic activity. However, the ratio between the emissions fluctuates around constant values over time and does not undergo significant changes throughout the entire PsA event, which can last for more than an hour.

“…It is dominated by the effects of atmospheric waves and oscillations with different scales, including ENSO, AO, SAO, QBO, planetary waves, tides, and gravity waves. Radar and lidar, using both groundbased and satellite-based optical instruments, are important observational tools in this region [1,2]. Furthermore, the method of the resonant scattering of radio waves on artificial periodic inhomogeneities (APIs) of the ionospheric plasma is used to conduct temperature measurements in the MLT region [3].…”
