“…The TUS detector, located on the Lomonosov satellite, measured the pulsations of near-UV emissions in the auroral region during periods of high-intensity, long-duration, continuous AE activity. Simultaneously, charged particle detectors such as DEPRON on the same spacecraft [17] and the MSGI-M and SKL-M detectors on the METEOR-M2 satellite [18] were used to measure the charged particle fluxes. These observations provide a hint of the potential relationship between high-energy electron fluxes and pulsating auroras.…”

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.
