We present concept of a new multi-satellite Universat-SOCRAT project aimed to study transient phenomena in the upper atmosphere such as transient luminous events (TLEs) and terrestrial gamma-ray flashes (TGFs). It is a new space project of Lomonosov Moscow State University based on the use of a few satellites in the near-Earth orbit for real-time monitoring of radiation environment, natural (asteroids, meteoroids) and artificial (space debris) potentially dangerous objects, electromagnetic transients including cosmic gamma-ray bursts, terrestrial gamma-ray flashes, and optical and ultraviolet bursts in the Earth's atmosphere. Study of TLEs and TGFs remains an important and demanding task despite of a multitude of recently acquired data for these phenomena. This might be explained by the absence of comprehensive theoretical understanding of physical nature of high-energy processes in the Earth's atmosphere. Multi-wavelength synchronous observations with moderate accuracy of localization of TGF and TLE events are necessary to gain an insight of physics governing these high-energy processes in the Earth's atmosphere. In the article, we present results of TLE observations in space experiments of Moscow State University and discuss advanced instruments for optical observations of TLEs, as well as gamma-ray burst monitor and tracking gamma spectrometer for TGFs observations.

“…This was proposed in 2009 [23]. The first mission of the UFFO project UFFO/Lomonosov [18,21] was developed and fabricated onboard the Lomonosov satellite, which was launched on 28 April 2016 [24]. After the launch, calibration of the satellite and payloads, including the UFFO/Lomonosov, was carried out for approximately seven months, but unfortunately, the operation was ended before any GRB data could be acquired because of a power supply failure in the satellite.…”

Detection of Low-Energy X-rays Using YSO Scintillation Crystal Arrays for GRB Experiments

et al. 2021

We developed an X-ray detector using 36 arrays, each consisting of a 64-pixellated yttrium oxyorthosilicate (YSO) scintillation crystal and a 64-channel multi-anode photomultiplier tube. The X-ray detector was designed to detect X-rays with energies lower than 10 keV, primarily with the aim of localizing gamma-ray bursts (GRBs). YSO crystals have no intrinsic background, which is advantageous for increasing low-energy sensitivity. The fabricated detector was integrated into UBAT, the payload of the Ultra-Fast Flash Observatory (UFFO)/Lomonosov for GRB observation. The UFFO was successfully operated in space in a low-Earth orbit. In this paper, we present the responses of the X-ray detector of the UBAT engineering model identical to the flight model, using 241Am and 55Fe radioactive sources and an Amptek X-ray tube. We found that the X-ray detector can measure energies lower than 5 keV. As such, we expect YSO crystals to be good candidates for the X-ray detector materials for future GRB missions.

В рамках нашего исследования было проведено сравнение вариаций числа корональных выбросов массы (КВМ) и крупномасштабных событий в солнечном ветре с суммарным числом внезапных импульсов в геомагнитном поле SI и внезапных начал геомагнитных бурь SSC в 23 и 24 циклах солнечной активности (CA). Сопоставлены вариации чисел солнечных пятен (чисел Вольфа) с циклическими вариациями появления КВМ за каждый месяц наблюдений коронографов LASCO в 23 и 24 циклах солнечной активности. Так же было исследовано соотношение изменений суммарного числа КВМ различного углового размера с суммарным числом зарегистрированных приходов к Земле межпланетных ударных волн, вызвавших внезапные импульсы в геомагнитном поле (SI) или внезапные начала геомагнитных бурь (SSC), и с суммарным числом крупномасштабных событий в солнечном ветре таких, как EJECTA и МС (Magnetic cloud) согласно каталогу ИКИ.
