Between 1972 and 2002 more than 5000 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 and 1997) are also reduced by the Dutch
Meteor Society and the results are included in the database.
Out of all multi station events 1344 meteors yielded orbital data. The 2001
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 2001.
Next update is expected mid 2004 and will include orbits of the 2002 Perseid
shower.
The DMS video database contains now orbital and trajectory data of 742
video multistation meteors, photographed by the Dutch Meteor Society up til 2000.
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 1972-2000 is available in Microsoft
Excel format (version 97) and in ASCII text format on the DMS ftp site.
