               Welcome !

The IAU Meteor Data Center (MDC) operates at the Astronomical Institute of the Slovak Academy of Sciences, under the auspices of Division F (Planetary Systems and Bioastronomy) of the International Astronomical Union (IAU).

The MDC is responsible for

  • the designation of meteor showers, in conjunction with the Working Group on Meteor Shower Nomenclature of IAU Commission F1 (Meteors, Meteorites, and Interplanetary Dust); it acts as a central list of all meteor showers (Shower database)
  • the efficient collection, (computation,) checking and dissemination of trajectory observations and orbits of meteors; it acts as a central depository for meteor orbits obtained by photographic, video and radar techniques (Orbital database)

The points of contact for reporting:

  • the discovery of a new or for reports of known meteor showers: mdc_showers [at]
  • the new measurements of meteor orbits and trajectories: mdc_orbits [at]

The IAU Meteor Data Center team:

  • Shower Database: Mária Hajduková (Astronomical Institute of the Slovak Academy of Sciences, Bratislava, Slovak Republic) and Regina Rudawska (RHEA group/ESA ESTEC, Noordwijk, The Netherlands).
  • Orbital Database: Luboš Neslušan, Marian Jakubík, Ján Svoreň (Astronomical Institute of the Slovak Academy of Sciences, Tatranská Lomnica, Slovak Republic).

Since its beginning, the IAU MDC database has been maintained on an unpaid voluntary basis.
