Meteor Databases

Version 2024

Welcome on the web pages of the Meteor Data Center (MDC) of International Astronomical Union (IAU).

The IAU MDC database has been created in purpose to provide to the researchers interested in meteor astronomy the precise, reliable, and complete-in-compulsory-parameters data, gained by using of various detection techniques. The set of these data is assumed to be used especially in the methodological studies. Because of a possibility of comparison between the corresponding results obtained by various authors or author teams, which is possible if all they use basically the same data, no often upgraded of these - nominal - data is supposed.

These pages contain the data and documentation to the photographic, video, and sample of radio-meteor catalogs. In total, the current version of the database contains 6 345 photographic, 962,773 (471,582 CAMS, 490,283 SonotaCo, and 908 DMS) video and 11,057,023 (8,916 Hisar and 11,048,107 SAAMER orbits) radio-meteor orbits.

The chosen data can be printed, or downloaded (year by year) in the PDF, Excel-table, or CSV format (the menu will appear after you choose the catalog(s) and parameters, and click "Submit"; the chosen data will then appear at the bottom of the page).

Or, the ZIP archive of very extended video data for a given year can also be downloaded (CSV format is packed).

The used catalog should be cited. The list of relevant references can be found here.
