Item IAU Meteor Data Center: the shower database(The National Academy of Sciences of Tajikistan, 2021) Jopek, T. J.; Kokhirova, G. I.; Jenniskens, P.; Janches, D.; Hajdukova, M.; Rudawska, R.The IAU Working Group on Meteor Shower Nomenclature was established in 2006 to regulate the nomenclature of meteor showers reported in the scientific literature. One year later the International Astronomical Union Meteor Data Center shower database was implemented (IAU MDC). The database does not contain all information about the meteor showers. Its purpose is to give each new meteoroid stream, published in the scientific literature, a unique name and codes. During the “Meteoroids 2019” conference held in Bratislava, the IAU Working Group on Meteor Shower Nomenclature established new rules for the introduction and removal of meteor showers from the MDC. In this paper, we present a concise description of the meteor shower database, its origin, and struc- ture and, in particular, the current requirements for the introduction of new data, and unknown as well as known meteor showers.Item Radio meteor data from the Hissar observatory in the IAU MDC database(Tajik Technical University, 2020) Narziev, M.; Chebotariev, R. P.; Jopek, T. J.; Neslusan, L. Z.; Porubcan, V.; Svoren, J.; Khujanazarov, H.F.The article deals with the results of a two-dimensional distribution of meteoroids over the equatorial and ecliptic coordinates of the radiants, velocities, and radio magnitudes of meteoroids. The coordinates of the radiant and the angular orbital elements correspond to the J2000 epoch. Radio magnitudes of meteors are concentrated in the range 0 ÷ 5.5 mag with a maximum at 3.3 mag. The data of 8916 radiometeors obtained by radar observations from 4 points at the Gissar Astronomical Observatory, Dushanbe, Tajikistan, have been added to the database of the Meteor Data Center of the International Astronomical Union.
