IAU MDC Meteor Orbits Database -- A Sample of Radio-Meteor Data from the Hissar Observatory
Abstract
We announce an upgrade of the IAU MDC photographic and video meteor orbits database. A sample of 8916 radio-meteor data determined by the radar observations at the Hissar (Gissar) Astronomical Observatory, Dushanbe, Tajikistan, are added to the database. Along with the radiant coordinates, velocities, and orbital elements the Hissar radio-meteor sample contains the heights, linear electron densities, stellar magnitudes, and masses of the meteoroids. The new 2018 version of the IAU MDC database contains 4873 photographic, 110521 video, and 8916 radio meteor records. The data are freely available on the website at the address https://www.astro.sk/~ne/IAUMDC/PhVR2018/ .
