Light Curve Tool for Small Bodies

Occultation Mode

This tool projects a 3D shape model of a minor body onto the sky plane for a given event date, using the sidereal rotation period and an epoch corresponding to a photometric maximum. Users can upload a custom shape model in .obj format or define the principal axes of a triaxial ellipsoid, and specify the rotation pole coordinates. The tool computes the correct rotational phase from the reference epoch and displays the on-sky silhouette of the body, which is especially useful for stellar occultation predictions and analysis. For more details, please refer to the manual.
