“…Moscow State University satellite “Universitetsky‐Tatiana‐2”(later‐ on Tatiana‐2 satellite) was launched on 20 September 2009 to solar synchronous polar orbit with the height of 820–850 km and inclination of 98.8° [ Sadovnichy et al ., ]. The main goal of the scientific program of this satellite as well as of the first satellite of the same class “Universitetsky‐Tatiana” [ Sadovnichy et al ., ] is a study of space near the Earth by measuring charge particle flux at the orbit and radiation from the atmosphere. The data discussed in this paper were collected from 20 October 2009 to 17 January 2010.…”

[1] Light detectors sensitive to wavelength ranges 240-400 nm and beyond 610 nm (which we refer to, for simplicity, as the UV and Red bands) on board UniversitetskyTatiana-2 satellite have detected transient flashes in the atmosphere of duration 1-128 ms. Measured ratio of the number of Red photons to the number of UV photons indicates that source of transient radiation is at high atmosphere altitude (>50 km). Distribution of events with various photon numbers Q a in the atmosphere found to be different for "luminous" events Q a = 10 23 -10 26 (with exponent of differential distribution -2.2) and for "faint" events Q a = 10 21 -10 23 (with exponent À 0.97). Luminous event parameters (atmosphere altitude, energy released to radiation, and temporal profiles) are similar to observed elsewhere parameters of transient luminous events (TLE) of elves, sprites, halo, and gigantic blue jets types. Global map of luminous events demonstrates concentration to equatorial zones (latitudes 30 N to 30 S) above continents. Faint events (with number of photons Q a = 10 20 -5Á 10 21 ) are distributed more uniformly over latitudes and longitudes. Phenomenon of series of transients registered every minute along satellite orbit (from 3 to 16 transients in one series) was observed. Most TLE-type events belonged to series. Single transients are in average fainter than serial ones. Some transients belonging to series occurs far away of thunderstorm regions. Origin of faint single transients is not clear; several hypothetical models of their production are discussed.Citation: Garipov, G. K. et al.

Detectors on the "Universitetsky-Tatiana" satellite measured a smoothly varying intensity of UV radiation from the night-time atmosphere in the nadir direction and the intensity of the energetic electron flux at the orbit. At high latitudes the UV intensity in the auroral oval is interpreted as being due to electrons penetrating into the atmosphere. At middle latitudes the UV intensity is an order of magnitude less and more data are needed to reveal the origin of this radiation. Millisecond flashes of UV radiation were observed. The flashes' energy, temporal profile and global distribution are similar to these parameters for Transient Luminous Events (TLEs). These studies will be continued aboard the next satellite "Tatiana-2".

V. A. Sadovnichii et al. zations to study some of extreme phenomena in space related to astrophysics, astroparticle physics, space physics, and space biology. The primary goals of this experiment are to study: -Ultra-high energy cosmic rays (UHECR) in the energy range of the Greizen-ZatsepinKuzmin (GZK) cutoff; -Ultraviolet (UV) transient luminous events in the upper atmosphere; -Multi-wavelength study of gamma-ray bursts in visible, UV, gamma, and X-rays; -Energetic trapped and precipitated radiation (electrons and protons) at low-Earth orbit (LEO) in connection with global geomagnetic disturbances; -Multicomponent radiation doses along the orbit of spacecraft under different geomagnetic conditions and testing of space segments of optical observations of space-debris and other space objects; -Instrumental vestibular-sensor conflict of zero-gravity phenomena during space flight. This paper is directed towards the general description of both scientific goals of the project and scientific equipment on board the satellite. The following papers of this issue are devoted to detailed descriptions of scientific instruments.
