Radiants and data


All high-level Global Meteor Network data products (radiants, orbits, magnitudes and masses) are public and are updated every 6 hours.

The data are released under the CC BY 4.0 license, so if you are using the data for scientific purposes, we kindly ask you to reference this web site in your work.

You can access the complete data set here: GMN data

And all plots here: GMN plots

Feel free to contact us if you need the data in a different format!

The radiant plots show the latest data and are in Sun-centered ecliptic coordinates. Figure 1 illustrates the coordinate systems and show example meteoroid orbits. The Earth's apex (direction of motion around the Sun) is in the center of the plot at 270°, the Sun is left at 0°, and the anti-helion direction is at 180°.

CMOR radiants

Current radiants by the Canadian Meteor Orbit Radar (CMOR). Note that CMOR observes 24/7 and can thus observe radiants in the helion source.
