MPC Submission InformationFor those wishing to submit astrometric observations for publication in the Minor Planet Circulars information is available on the format of astrometric observations. Observations, formatted as described therein, should be sent to
email@example.com. Reports for new comets should also (following the redistribution of tasks at the 2015 IAU GA) be reported to the MPC. Note that visual reports of comet discoveries should be reported to
Further technical information on Minor Planet Center submissions is available:
- Observation format
- Indication of observational details
- Orbit format (export)
- The HTML pages describing the new format for import of orbital elements will be available here at some future date.
- Orbit format (import)
Orbits submitted for publication in the MPCs need to be in a

- Indication of perturbing bodies for orbits
- Alphabetic notes for orbits
- Calculation of the orbital-uncertainty parameter, U
- Guide to Minor Body Astrometry: Notes for new or potential astrometrists

- Links to various technical lists
- These lists contain low-level information generated during MPC filing operations and are not formatted for casual viewing. They are generated from files that are updated with each batch of Minor Planet Circulars and should be complete through observations processed up to the cutoff date for inclusion of the latest MPC batch.
