Jeong Department of Physics, Sungkyunkwan University, Seobu-ro, Jangangu, Suwonsi, Korea A.J.Castro-Tirado IAA-CSIC, Granada, Spain Russian space mission "Lomonosov" (*) ( http://lomonosov.sinp.msu.ru/en/ ) was launched 28.04.2016 from new Russian Kosmodrom "Vostochny" to polar solar-synchronous orbit with altitude ~490 km. Scientific program of "Lomonosov" includes a multi-wavelength GRB study at different time scales. In particular the complex study of prompt emission will be provided based on the direct recording of readings of wide field optical cameras as well as on the fast pointing of optical and UV telescope using its moving mirror. The spacecraft "Lomonosov" contains 3 instruments for GRB study: gamma-ray burst monitor BDRG ( http://lomonosov.sinp.msu.ru/en/scientific-equipment-2/bdrg ), a wide field optical camera SHOK ( http://lomonosov.sinp.msu.ru/en/scientific-equipment-2/shok ) and UFFO ( http://lomonosov.sinp.msu.ru/en/scientific-equipment-2/uffo ) instrument consisting of coding mask X-ray telescope UBAT and UV slewing mirror telescope SMT. The Lomonosov GRB monitor BDRG is designed to obtain temporal and spectral information about GRBs in energy range 10-3000 keV as well as to produce GRB trigger. The trigger is used onboard to fix some amount of data before GRB stored in the internal memory of all instruments of GRB complex as well as to start the detailed data collection. Immediately after the trigger the onboard estimation of the GRB position starts. Then the telegram with trigger information is sent via Global Star transmitter to the server in MSU and, after automatic ground-based data processing (to exclude radiation belt zones etc.) to GCN (this will be realized sometime later after optimizing the trigger parameters during flight tests). There are 3 GRBs and 5 SGR outbursts are detected to the present BDRG GRB monitor, which were also detected by other space missions and presented in GCN: GRB 160703 12:10:02 UTC GRB 160705 17:40:19 UTC GRB 160720 18:27:55 UTC Bursts from SGR1935+2154 18.06.2016 20:27:24 UTC, 20.06.2016 15:16:34 UTC, 23.06.2016 21:20:45 UTC, 23.06.2016 21:23:35 UTC, 26.06.2016 13:54:29 UTC Press release is available at http://lomonosov.sinp.msu.ru/wp-content/uploads/GRB_by_BDRG_engl_pdf.pdf The message may be cited.
