Abstract: On April 2025, the IAU Meteor Data Center team, part of orbital database, issued the new version of the orbital database, Version 2025. Its content considerably increased. The video EDMOND, GMN, and radio AMOR data are included.

 

Announcement

The IAU Meteor Data Center (MDC) is a central repository of the orbital and other data of individual meteors (MO part of the MDC) and the official database of known meteor showers (SD part). We announce that the orbital database was recently enlarged including: 2001–2017 EDMOND (European viDeo MeteOr Network Database) (Kornoš et al., 2014a; Kornoš et al., 2014b), 2018–2024 GMN (Global Meteor Network) (Vida et al., 2020; Vida et al., 2021), 2024 SonotaCo (SonotaCo et al., 2021), and 1990–1999 AMOR (Advanced Meteor Orbit Radar) (Baggaley, 1983; Baggaley et al., 1993; Baggaley, 1996; Baggaley, 1999) data.

The new – Version 2025 – IAU MDC database contains:

  • 6345 – photographic meteor orbits (42 individual catalogs);
  • 3206547 – video meteor orbits (5 catalogs);
  • 11937769 – radar meteor orbits (3 catalogs).

The IAU MDC public-domain data can be downloaded, all catalogs in the same format, from the MDC site:

The orbital part is accessible online.
