The VMDB contains about 3,000,000 meteors obtained by standardized observing methods which were collected during the last ~25 years. The actual database is stored in dBase format; extracts in ASCII format can be downloaded from VMDB page.
VISDAT provides a data base system together with software designed to helps observers handle and utilize their observations. It allows preliminary analysis of the data for direct feedback to the observer's skills, and exports to other databases such as the VMDB and PosDat. In contrast to those systems, the VISDAT package preserves the complete information of an observing session. The archive contains nearly 30000 individual meteors observed over more than 2000 hours.
The Video Meteor Database is currently kept on the IMONET Homepage and contains video data of about 420,000 meteors recorded over nearly 3200 nights. The oldest records date back to 1993. The data is available as dBase files from http://www.imonet.org/database.html.
The MSSWG orbit database contains multi-station video meteor data from the Japanese MSSWG. The Meteor Science Seminar (MSS) was founded on October 8, 1978. The seminar is convened four times a year in Tokyo, Japan, for studying about meteors. The Meteor Science Seminar Working Group (MSSWG) was organized in this connection. Until 1992, it had been engaged in double-station photographic meteor observations, and since 1993 it has pursued double-station TV meteor observations.
The Radio Meteor Observing Bulletin (RMOB) is an independent initiative of some workers in the field of radio meteor scatter observations and data reduction. It started in August 1993 in order to spread the Perseid results via E-mail. Since then, it has appeared monthly, and it has gradually been expanded. In regularly publishing summaries of observations, potential radio observers are kept up to date of existing installations, possibilities and limitations of radio meteor observations.
On these pages you can find conversion tables between solar longitude and "normal" dates. All solar longitudes refer to equinox J2000 and have three significant decimals. The longitudes are given in 2-hour steps for each day of the years.
The solar longitudes are also available for download as text files.
