Photographic Orbits
Updated November 1, 1999


Between 1979 and 1998 more than 1800 meteors have been photographed by two or more stations of the small camera network of the Dutch Meteor Society. Most multi station events were photographed in the Netherlands but also many orbital and trajectory data were gathered at expeditions abroad. Data from the Californian network (from 1994 onwards) are also reduced by the Dutch Meteor Society and the results are included in the database.
Out of all multi station events 985 meteors yielded orbital data. The 1998 version of the DMS photographic database consists of all photographic orbits obtained from the early beginning of the Dutch Meteor Society in the seventies until and including 1998.

The DMS photographic database is available in two formats:

DMSPRC98.xls.zip DMSPRC98.mdb.zip
(Excel 97 - 183 kB)(Access 97 - 175 kB)

The .mdb version also contains several queries.
Both files can be downloaded as .zip files.

Video Orbits
Updated January 23, 1999


The DMS video database contains now orbital and trajectory data of 563 video multistation meteors, photographed by the Dutch Meteor Society up til 1998. Orbital data of the 1995 Quadrantids, the 1995 Leonids and alpha Monocerotids and the 1993-1998 Perseid (outbursts) streams have been published in several journals. See the DMS publications list, abstract service and full papers on the DMS web site and DMS ftp site. Now the full table of video data 1972-1998 is available in Microsoft Access Database format (.mdb for version 97) and in Microsoft Excel format (version 97) on the DMS ftp site.

The DMS video database is available in two formats:

DMSVID98.TXT DMSVID98.XLS
(Text - 117 kB) (Excel 97 - 431 kB)
