- Аннотация: The Lomonosov satellite was launched into a 97.3° polar sun-synchronous orbit on April 26, 2016, and operated in orbit until December 2017. The TUS detector is a highly sensitive telescope, designed for both detection of ultra-high-energy cosmic rays and the Earth’s atmosphere UV-radiation in the 240–400 nm range. To measure variety of atmospheric phenomena the telescope has four modes of operation with different temporal resolutions (from 0.8 µs to 6.6 ms). Among the events recorded above 50° N in the mode with a temporal resolution of 6.6 ms, 66 were identified with an unusual spatiotemporal structure, representing local pulsations of glow in the field of view of the instrument. Geographical distribution was analyzed and it was shown that events are mainly located in the area of equatorial boundary of auroral oval (more than half of events were registered on L-shells 4–6). Characteristic frequencies of pulsations of glow intensity are of the order of 1–10 Hz, and areas of pulsating glow are localized in the space with characteristic horizontal size of 10–15 km. A comparison with the THEMIS ground-based all-sky cameras was made. 11 joint observations were found and the presence of aurora lights at the time of TUS events registration was shown by ground-based cameras, although no obvious coincidences of pulsations were found.
